Telix v3.22 Introduction 1
1. INTRODUCTION
1.1 Program Description
──────────────────────────────────────────────────────────────────────
Telix is a full-featured communications program for PCs running the
PC/MS-DOS operating system, that is able to meet the needs of almost
any user. Telix features include:
■ An extensive range of built-in file transfer protocols, including
Zmodem, Compuserve Quick B, Xmodem, Xmodem-1k, Xmodem-1k-g, Ymo-
dem (TRUE), Ymodem-g, Kermit, SEAlink, Telink, Modem7, and ASCII.
Telix allows up to five 'external' protocols to be defined and
called from within Telix. In this way, almost any kind of file
transfer is possible from within Telix.
■ Powerful multiple dialing directories, holding up to 1000 entries
each. An entry contains many pieces of information required for
communicating with remote services, such as the phone number and
communications parameters.
■ Automatic queue redialing for hard-to-reach numbers.
■ Reliable DEC VT100/102 and VT52 terminal emulation. Keys may be
redefined by the user.
■ Extensive SALT script language which allows Telix to perform au-
tomated logons and many more complicated functions. As an example
of the power of script files, the Telix Host Mode is written in
the SALT script language.
■ Full access to DOS including a DOS shell, a DOS Command option,
and full path support.
■ A very advanced Host mode which can be run as a standalone
bulletin board system.
■ A Chat Mode, keyboard macros, a scroll-back buffer, session cap-
ture, usage log, translate table, and a variety of other fea-
tures, detailed in this manual. Above all however, Telix is FAST,
and has a powerful, friendly, user interface.
1.2 The Telix Philosophy
──────────────────────────────────────────────────────────────────────
When Telix was written, a basic idea was kept in mind. It was felt
that a powerful program could be simple to operate, with no loss of
speed in order to achieve this ease of use.
Telix v3.22 Introduction 2
1.3 Machine Requirements
──────────────────────────────────────────────────────────────────────
Telix will run on an IBM PC, XT, AT, PS/2, or true compatible with one
hard drive and one floppy drive, or two floppy drives, and with at
least 205k of free memory. This is memory available after DOS has been
loaded. For a few functions, such as the DOS Shell, more memory is
helpful. Telix will support up to 8 defined comm ports (COM1 through
COM4 are predefined), any number of disk drives, and a printer con-
nected to the parallel port.
To get full use of Telix your modem must meet certain standards as
well, especially for the Host Mode script. The Carrier Detect signal
should not be forced high (on) by the modem, so that Telix can tell
when you are online. This is usually controlled by the setting of a
dip switch on the modem, or a modem command (often &C1). The DTR (Data
Terminal Ready) signal should not be ignored by the modem (&D2 in many
cases, or switch controlled).
1.4 Telix Files
──────────────────────────────────────────────────────────────────────
Telix comes with a number of files and creates more in its normal op-
eration. Some files included in the Telix package are:
TELIX.EXE The Telix program itself
TELIX.DOC The Telix program reference manual
MODEMCFG.EXE The Telix modem configuration program
TELIX.MDM Data file for MODEMCFG
CS.EXE The SALT script language compiler
CSS.EXE The SIMPLE script language compiler
SALT.DOC The SALT script language reference
SIMPLE.DOC The SIMPLE script language reference
QDHOST.SLT The QDHost Mode script file (source)
QDHOST.SLC The QDHost Mode script file (compiled)
QDCONFIG.SLT QDHost Mode configuration script (source)
QDCONFIG.SLC QDHost Mode config. script (compiled)
HOSTPLUS.DAT Compressed HOSTPLUS advanced BBS
HOSTPLUS.DOC The HOSTPLUS program reference manual
HINSTALL.EXE The HOSTPLUS installation program
*.KEY The various key definition files for the ter-
minals supported by Telix
If your copy of Telix came in PKZip format then these files should be
accompanied by a PKZip authenticity verification number of MUP129
bearing a deltaComm message. If your .ZIP files do not carry the PKZip
authenticity stamp, you should question their integrity, or upgrade to
PKZip 1.10 to insure that the AV stamps are there. PKZip 1.02 or
earlier cannot display AV information.
Files (optionally) created and used by Telix include:
TELIX.FON The default dialing directory file
Telix v3.22 Introduction 3
TELIX.LD The Long Distance Codes file
TELIX.CAP The default session capture file
TELIX.IMG The screen image save file
TELIX.KEY The default user key macros definition file
QDHOST.CNF The Host Mode configuration file
Telix at one time or another can have a number of files open, espe-
cially during Host Mode and a few other instances. If Telix tells you
it is having problems opening files then it is probable that including
the line:
files=20
in your CONFIG.SYS file could clear up the problem. This allows DOS to
open more files (the default is 'files=8'). For more information on
the CONFIG.SYS file see your DOS manual.
1.5 Start-Up Directory
──────────────────────────────────────────────────────────────────────
When you run Telix it will remember the disk directory you ran it
from. After this point, even if you have changed the current directory
with the 'Change directory' command, Telix will know that it should
look for its program files on the start-up directory. Some files will
also be written on this directory unless you specify another.
If you set the environment variable 'TELIX', Telix will have another
(even better) way of knowing where to look for its files. The command
form at the DOS prompt is:
set TELIX=pathname
where pathname is a the legal DOS pathname of the directory in which
the Telix files are located. Do not leave any space between the '='
and the arguments. For example, if you used 'set TELIX=C:\TELIX\',
Telix would know to look for its files in the Telix directory on drive
C. This way, no matter where you run it from, Telix will always be
able to find its files. To reset this environment variable to nothing
the command is:
set TELIX=
For more information on environment variables see your PC/MS-DOS man-
ual.
Telix v3.22 Getting Started 5
2. GETTING STARTED
2.1 Configuring Telix with MODEMCFG.EXE
──────────────────────────────────────────────────────────────────────
Telix has a complete setup program that will create or modify your ex-
isting configuration to work best with your modem, and will modify
your modem settings to work best with Telix. To run the configuration
program, from the DOS prompt type:
MODEMCFG
The files TELIX.MDM and MODEMCFG.EXE must be in the same subdirectory
as TELIX.EXE for proper use. If INSTALL.EXE was used properly, or all
.ZIP files were extracted into the same subdirectory, this will be the
case. The TELIX.MDM modem information file will be updated on the
Telix BBS regularly to handle changes in modem strings and to add new
modems and models.
Throughout the menus of MODEMCFG.EXE, you may use the arrow keys to
move in a given direction, Tab and Shift-Tab to move right or left,
Home, End, PgUp and PgDn to move up or down, or press the first letter
of the menu item to move to the next item beginning with that letter.
A menu will be shown from which you should select the manufacturer of
your modem. If your modem manufacturer is not one of the options, se-
lect generic, or contact deltaComm to have it added.
Under each manufacturer is a list of their modems. Again pick the ap-
propriate modem.
You will be shown a list of the settings for the modem itself, includ-
ing any switch settings if known. Please write down the switch set-
tings as you will need them later. When asked if you wish to configure
your modem, answer by pressing the 'Y' key. MODEMCFG will ask you for
your comm port as well. Please refer to your modem manual for this in-
formation.
If all goes well a successful configuration message will be shown. If
there is a problem, insure the proper comm port is specified and try
again. If the problem persists, contact deltaComm.
A similar setup procedure will take place for TELIX.CNF, the configu-
ration file for Telix itself. MODEMCFG will only change the values
pertinent to the performance of the modem in existing configurations.
Any existing color values or preferences will be left intact. If
TELIX.CNF does not exist, MODEMCFG will create it.
Telix v3.22 Getting Started 6
The exit screen of MODEMCFG contains final instructions on how to make
best use out of the setup that has been written for you. Please make a
note of these for later referral.
You are now ready for your first Telix session.
2.2 Starting a Telix Session
──────────────────────────────────────────────────────────────────────
To start the Telix program type the following while at the DOS prompt:
Telix [O][Q][B][D] [Sfilename] [Cfilename] [Ffilename]
The letters in the square brackets are optional command line switches
affecting what Telix will do upon start-up. The square brackets should
not be entered. The order and case of the options does not matter but
they must be separated by at least one blank.
Specifying the 'O' option upon start-up tells Telix that you are al-
ready online (connected to a host systems), and that it should not try
to initialize the modem.
The 'Q' option in the command line chooses quiet mode for the current
session. When quiet mode is on Telix will not sound any alarms (e.g.,
when a file transfer is over), no matter what the default setting for
alarms is. This is useful for those late night sessions. Any bell
characters sent by the remote system are still sounded however.
Specifying 'B' in the command line forces Telix to use the PC's BIOS
for all screen write operations, whatever the default setting for
screen writes might be. This is useful when you want to run Telix in a
multi-tasking environment such as Topview or MS Windows for just one
session. Note that Telix is DESQview aware, so you do not have to use
this mode for DESQview.
The 'D' option forces Telix to drop RTS during disk writes for those
systems exhibiting frequent errors at rhythmic intervals while
downloading. This is called slow handshaking.
The 'S' option indicates that a script file (explained elsewhere) is
to be run immediately upon start-up. The 'S' should be followed imme-
diately (no blanks) by the name of the script file to execute.
The 'C' option indicates that another Telix configuration file than
the standard TELIX.CNF should be used. If it doesn't exist, it will be
created. In this way, you may have multiple configurations for Telix.
The name of the configuration file should immediately follow the 'C',
and should include the extension.
The 'F' option indicates that another dialing directory (FON) file
than the default TELIX.FON should be loaded at start-up. The name
should immediately follow the 'F'. Note that another dialing directory
Telix v3.22 Getting Started 7
file may also be loaded from within Telix (in the dialing directory
screen).
Upon starting, Telix will display a title screen for a period of 25
seconds or until you press a key. Please read the message on the title
screen carefully. After you are past the title screen, you will be in
'terminal mode' unless Telix can't find the configuration file
(usually TELIX.CNF), in which case it will ask you a few questions
about your machine and modem, and then will write a configuration file
for you.
2.3 Terminal Mode
──────────────────────────────────────────────────────────────────────
Immediately after starting Telix, and for most of the time while using
it, you will be in Telix's terminal mode. While in this mode any nor-
mal (ASCII) characters you type will be sent to the modem port, and
any incoming characters will be printed on the screen. It is from the
terminal mode that most Telix commands are initiated. Most commands
are selected by pressing two keys at the same time. For example, to
access the dialing directory, you would press Alt-D. That is, while
holding down the Alt key, you press the D key.
2.3.1 The Help/Status Screen
While in terminal mode, pressing the Alt-Z sequence will switch you to
a help screen showing you a summary of all the available commands. If
the key for a command is pressed while the help screen is still on,
the screen will be turned off and the command will be executed.
On the bottom of the help/status screen is some information regarding
some current settings and the status of the current connection, as
follows (in slightly compressed form).
╒══════════════════════════════════════╤═════════════════════╕
│ Time..10:39:00 Online .... No │ Capture...Off │
│ Date..06-29-91 │ Printer...Off │
│ Baud..2400 Terminal .. VT102 │ Script....None │
│ Comm..N,8,1 Port ...... COM1 │ Reg. Key..TELIX.KEY │
│ Echo..Off Add LF .... Off │ Dial Dir..TELIX.FON │
╘══════════════════════════════════════╧═════════════════════╛
Items included are: the current time and date, the connect status, the
elapsed time for the call in progress, the current communications
parameters, the state of the capture file and printer, the currently
executing script file (if there is one), the current dialing direc-
tory, the current keyboard macro definition file, and a few other
items.
Telix v3.22 Getting Started 8
2.3.2 The Status Line
Telix has an optional status line which may be displayed at the bottom
or top of the screen (it may be controlled via the Telix Configuration
Menu, or toggled on/off by pressing Alt-8 in terminal Mode). The sta-
tus line displays the current communications setting such as baud rate
and parity, the state of the Capture file, whether or not the printer
is on, the currently executing script file (scripts are explained
elsewhere), and whether Telix is On-line or Off-line. The following is
an example of a status line, and what each section can contain:
┌─────────────────────────────────────────────────────────────────────┐
│ The Status Line example screen display can not be shown in the DOC │
│ file format Telix manual, due to width limitations. │ │
└─────────────────────────────────────────────────────────────────────┘
2.4 Communications Parameters
Pressing Alt-P allows you to change the Communications Parameters.
This is the format in which Telix sends data over the modem, and ex-
pects to receive it in. After pressing Alt-P a window is displayed
with the current parameters at the top, and the options in the rest of
the window. To change a value press the letter or number of the set-
ting you want.

bps rate, which stands for bits per second). 1200 baud and 2400 baud
are the two most common speeds in use, and represent about 120 and 240
Telix v3.22 Getting Started 9
characters per second, respectively. Baud rates all the way up to
115200 are supported by Telix, however a fast PC is needed for the
higher rates (a stock 4.77 MHz XT can handle 9600 and possibly 19200
baud, higher rates need an AT class computer). Parity is a form of er-
ror checking. Allowable parities are None, Even, and Odd. Data bits is
the number of bits (a bit is a one or a zero in a computer) in each
character. Allowable values are 7 and 8. Finally, the number of stop
bits parameter can be set to either 1 or 2. The most common format for
BBS use is a baud rate of 1200 or 2400, 8 data bits, no parity, and 1
stop bit. On many large networks such as Compuserve, the data format
used is E71.
The communications parameters menu also allows you to select the com-
munications port you want to use. Note that by default only the first
four comm ports are defined (the last four are duplicates of COM1).
Changing any parameters changes them only for the duration of the cur-
rent communications session. If you want a set of parameters to be the
default when you start Telix, use the Telix Configuration Menu, Alt-O.
2.5 Using Telix Menus
──────────────────────────────────────────────────────────────────────
Whenever Telix must ask you to select an item from a group of options,
it uses the same basic type of menu. The options will be arranged ver-
tically for a vertically oriented menu, and next to each other for a
horizontally oriented menu. There are two ways to select the item that
you want. Each menu option has one of its letters in bold text; press-
ing that letter will select the corresponding option. As well, one op-
tion in the menu is always highlighted in inverse video. The arrow
keys on the PC's keypad will move the highlight up and down or left
and right. When the highlight is over the option you want to select,
press Carriage Return, or Enter.
2.6 Entering and Editing Strings
──────────────────────────────────────────────────────────────────────
While using Telix, you will often have to enter a string of charac-
ters, for example a filename, or a list of numbers to dial. Telix
gives you full editing powers when you enter a string. As you type
characters, you may use the Backspace key to delete previously entered
characters. The Left and Right arrow keys allow you to move back and
forth in the string to edit what you have entered. By default, any
characters you enter overwrite any that are already there. Pressing
the Ins key will place Telix in insert mode, and any existing charac-
ters are pushed ahead as you type. Pressing Ins once more places you
back in overwrite mode. Home and End place the cursor at the
beginning or end of the string, respectively. Finally, pressing the
Ctrl-Left and Ctrl-Right arrow keys allows you to move back and forth
in the string by increments of a word.
Telix v3.22 Getting Started 10
2.7 Output String Translation
──────────────────────────────────────────────────────────────────────
In quite a few instances while using Telix, the user must specify a
string to be sent out over the modem port. Sometimes this string must
contain characters which can not be printed on the screen, for exam-
ple, control characters, and even pauses. There has to be a way of in-
dicating these special characters, and it is done through the use of
special characters called translation characters. When these transla-
tion characters are encountered in an output string they are trans-
lated into other characters. The default translation characters are:
^ when this character is encountered in an output string
it will make the following character a control charac-
ter. For example, ^A will send out the code for Con-
trol-A. A few common control characters are ^M, which
is the Carriage Return character, ^J, which is the Line
Feed character, and ^[, which is the Esc character. To
send out the ^ character itself, use two ^ characters,
as explained above.
~ when this character is encountered it will make Telix
pause for 1/2 a second. Note that the only way to send
a ~ character out is to use the sequence ^~ using two ~
characters in a row will simply make Telix pause twice.
There is one thing to keep in mind. These characters are only trans-
lated on strings sent out to the modem, for example, the dialing pre-
fix, the hang-up string, a keyboard macro, the modem initialization
string, and a few other cases.
2.8 Ending a Telix Session
──────────────────────────────────────────────────────────────────────
To exit the Telix program, press Alt-X. Telix will ask you if you re-
ally want to exit. Press 'Y' to confirm the exit, 'N' or Esc to return
to Telix.
If Telix detects that you are still on-line (connected to another com-
puter), it will also present a third option, 'Hang-Up'. If this option
is selected, Telix will make sure that the connection is broken before
exiting.
Telix v3.22 Program Features 11
3. PROGRAM FEATURES
3.1 Hang-Up
──────────────────────────────────────────────────────────────────────
Pressing Alt-H will make Telix attempt to hang-up the modem. Unless
this is disabled in the configuration Menu, Telix first attempts to
hang up the modem by turning off a signal on the RS-232 port called
the DTR line. This works with most modems. If this doesn't work, Telix
then sends the hang-up string defined in the Configuration Menu to the
modem. If this still doesn't work and Telix detects that you are still
online, Telix will warn you. If Telix is consistently telling you that
hang-ups fail even when they work, your modem is almost certainly
overriding the Carrier Detect signal. See the appendix on common prob-
lems for the solution to this.
3.2 Capture File
──────────────────────────────────────────────────────────────────────
Telix allows you to capture (record) data coming in from the comm port
and printed on the terminal screen, to a disk file. To open the cap-
ture file, press Alt-L. You will be prompted for the filename to save
the log to. Press Return to use the default filename. All data is
added to the end of the file if it exists already. To turn off the log
press Alt-L again and select the "Close" option. To temporarily pause
capturing data to the file, press Alt-L and select the "Pause" option.
While capturing is paused, any characters received are not saved to
the file. To then un-pause capturing, press Alt-L and select the
"Unpause" option.
3.3 Printer
──────────────────────────────────────────────────────────────────────
The printer may be toggled on and off by pressing Ctrl-@ to record in-
formation coming in from the comm port and printed on the terminal
screen. If Telix hangs when printer logging is turned on, the printer
is turned off, and should be turned on to proceed.
3.4 Usage Log
──────────────────────────────────────────────────────────────────────
Telix allows a usage log to be opened, which keeps track of calls you
make and file that you transfer. This is handy for keeping a record of
your long distance calls, for example. The Usage Log is toggled on and
off with the Alt-U key. If it is currently closed, you are prompted
for the name to open it to (TELIX.USE is the default). If it is cur-
rently opened, then it is closed. You may also set the Usage Log to be
opened by default at Telix start-up (via the Configuration Menu).

3.5 Scroll-Back
──────────────────────────────────────────────────────────────────────
To review past screens of characters press Alt-B. You will be in the
Scroll-Back display. You will be able to move through the last one
thousand to 64 thousand characters received (depending on the setting
in the Configuration Menu) by using the arrow keys to scroll line by
line, the Home and End keys to go to the beginning and end of the
buffer, and the PgUp and PgDn keys to scroll through the buffer a page
at a time.
To find a certain string in the buffer press 'F'. Telix will prompt
for the string to search for. If the string is found the line contain-
ing it will be placed at the top of the screen. To search for the same
string as last time press Return when asked for the search string.
To save the screen image to a file press 'I'. Telix will prompt you
for the file to save the image to. If the file already exists, the
screen image will be appended to it. To print out a screen image to
your printer press Shift-PrtSc.
3.6 Keyboard Definitions/Macros
──────────────────────────────────────────────────────────────────────
Telix will let you assign text to a key so that it is sent to the comm
port when that key is pressed. This is usually called a keyboard
macro, and is useful in saving keystrokes (for example, you can assign
your name to a key). Telix actually keeps two key definitions tables
in memory at all times (each table holds the text assigned to each
key), the user table and the terminal table. The terminal table is
used for terminal emulation key assignments. When Telix is told to
start emulating a certain terminal, it loads into this table defini-
tions specific to that terminal. Therefore, for each terminal there is
a key definition file which is loaded as needed. The user table on the
other hand is relatively constant. You might want to assign your name
to the Atl-1 key for example. This kind of definition would be put in
the user table.
When a key is pressed, Telix follows this procedure: If there is a
definition for that key in the terminal key table, send that text;
otherwise if there is a definition in the user table for that key,
send the text; otherwise if the key represents an ASCII value, send
that value; otherwise if the key is a Telix command (like Alt-D), per-
form that command.
The keyboard definition/macro editor is entered with the Alt-K key se-
quence from terminal mode. Telix will ask you if you want to access
the user or the terminal key definition table. Unless you wanted to
modify the keys for a specific terminal, you would always select the
user table. Telix will present the following menu:
Load Save Clear Display displayKey Edit eXit
Telix v3.22 Program Features 14
To load definitions from a previously saved key definition file into
memory, select the 'Load' option. Telix will ask for the name of the
key definition file (and use the extension '.KEY' if none is speci-
fied). Current key assignments will be cleared. The standard key defi-
nition file is "TELIX.KEY" and is loaded at start-up if it exists.
To save the current key definitions to a disk file, select the 'Save'
option. Telix will ask what file to save them to, and use the exten-
sion '.KEY' if none is specified.
Selecting 'Clear' will clear all the current key definitions in this
table.
Selecting 'Display' will show what text is assigned to each key.
Selecting 'displayKey' will allow you to look at what is assigned to
one specific key, by pressing it when prompted.
To actually enter or edit the text assigned to a key, select 'Edit'.
Telix will print the existing definition and allow you to edit it. En-
ter the characters that you want the key to send when pressed. Control
characters and pauses can be included in the definition in the manner
described previously in the manual under Output String Translation.
Remember that if you make any changes they will be lost when you exit
Telix unless you use the 'Save' option as described above, to save
them to disk.
Telix also allows you to run a script file when a certain function key
is pressed. If a function key definition has an '@' character as its
first character Telix will assume the rest of the definition is the
name of a script file, and will try to execute it. For example press-
ing the function key whose definition is '@logon' would run the script
file called LOGON.SLC. If you really want to send out an '@' character
as the first character in the key definition, then use two of them in-
stead. e.g., the definition '@@Hello' would send out '@Hello'.
3.7 DOS Shell
──────────────────────────────────────────────────────────────────────
Pressing Alt-J will let you jump to a DOS shell. You will see the DOS
prompt and will be able execute any DOS command, for example 'dir'. If
there is enough memory left, you can even run programs. There is an
option described later in the configuration section that allows you to
free up most of the computer's memory when shelling to DOS. To exit
the DOS shell type 'exit' and press Return. You will be back in Telix
with the screen undisturbed from before your jump to the shell. In
order to run the DOS shell, there must be enough memory left, and
Telix must be able to find the file called COMMAND.COM. If either of
these requirements is not met, Telix will tell you so. (The file
COMMAND.COM is the DOS command interpreter. It is usually pointed to
by the DOS environment variable COMSPEC. See your DOS manual for more
information). If you run a serial port related program in the shell,
there is a good chance that it will re-initialize the com port and
Telix v3.22 Program Features 15
another piece of information called the com interrupt vector. If this
happens, Telix will notice and re-initialize the port to the old
values when you return from the shell.
3.8 DOS Command
──────────────────────────────────────────────────────────────────────
Pressing Alt-V allows you to enter one DOS command or filename to run.
This command is then executed and control is returned to Telix. As can
be seen this is similar to the DOS shell, but is useful when you have
only one command to enter. There are many uses for this command. For
example, if your file viewing utility is called 'List', you could
press Alt-V and then enter 'List TELIX.DOC'. This would load your file
view utility and let you look at the TELIX.DOC file. After you termi-
nated this program you would be back in Telix. Any DOS command is le-
gal, for example 'copy a:*.ZIP c:', or 'ren data dat1'. If for some
reason you might want Telix to pause after the command is finished,
add a ';' character to the end of the command string, for example
'type TELIX.DOC;'. This stops the last screen-full typed from
scrolling by too quickly when control returns to Telix.
3.9 Editor
──────────────────────────────────────────────────────────────────────
Pressing Alt-A will allow you to run your favorite editor from within
Telix. In order to do this you must go to the Configuration Menu and
supply the full name and path of your editor in the 'Filenames and
paths' area. As well, there must be enough memory left, and if you
specified a batch file to be run, Telix must be able to find the DOS
command processor COMMAND.COM.
3.10 DOS and File Functions
──────────────────────────────────────────────────────────────────────
Pressing Alt-F will display a menu of some common DOS operations. For
convenience, a few commands available elsewhere have been included.

Telix v3.22 Program Features 16
Jump to DOS Shell
This performs the same function as the Alt-J command.
Files Directory
Telix will prompt you for the optional filespec, for example,
*.DOC. If you want to list all the files in the current directory
then just press Return. Telix will then do one of two things. If
you have defined a directory program to use (in the Configuration
Menu), Telix will run it. Otherwise Telix will use its own inter-
nal directory program, which is similar to the DOS 'dir' command
but also displays the time it would take to transfer each file
shown. The time is correct for the current default upload file
transfer protocol.
Change Drive/Directory
The current directory is displayed and you are asked to enter a
new one. You can enter a new drive, a new directory, or both.
This will become the current directory. Note that this is
slightly different from the DOS 'chdir' command.
Delete File
You are asked to enter the filename of the file to delete.
DOS Command
This performs the same function as the Alt-V command.
Run Editor
This performs the same function as the Alt-A command.
3.11 Screen Image
──────────────────────────────────────────────────────────────────────
Pressing Alt-I saves an image of the screen to the Telix Screen Image
file. This file is usually called TELIX.IMG, but can be renamed in the
Configuration Menu. If the file exists, the image is added to the end
of it.
3.12 The Translate Table
──────────────────────────────────────────────────────────────────────
Sometimes it is necessary for certain incoming or outgoing characters
to be changed to another value or stripped altogether. For this pur-
pose, Telix keeps in memory an incoming and an outgoing character
'translate table'. For every character in the ASCII set, the table de-
fines what it should be changed to. By default, no character transla-
Telix v3.22 Program Features 17
tion is performed, as for each character, the new value is defined to
be the same as the old one. The translate table facility is entered by
pressing Alt-W while in terminal mode. Telix will ask whether you want
to work with the incoming or outgoing table, and then display the
translate table screen with the following menu at the bottom:
Load Clear Save Edit Other eXit
Most of the screen is used to display translation values. Each column
holds on the left the original character (ASCII value), and on the
right the new character. Only half the ASCII set can be displayed on
one screen. Select the 'Other' option to toggle the display to show
the other half of the character set.
The 'Load' option is used to load a previously saved translate table
definition file. Telix will ask for the filename, including extension.
The 'Clear' option is used to reset all values in the translate table
in memory, so that no translation is performed.
The 'Save' option is used to save the current translate table defini-
tion to a disk file. Telix will ask for the file name to save the
table to. You must include the extension if needed (a common extension
for this purpose is '.XLT").
The 'Edit' option is used to actually edit the translate table. Telix
will ask for the old ASCII value, and the new one. If the new value of
a character is defined as 0, that character is completely striped.
It is sometimes useful to have an incoming and/or outgoing translate
table load automatically when Telix is run. If the file TELIXIN.XLT
exists at Telix start-up, it is assumed to be a default incoming char-
acter translate table, and is loaded into that slot. Similarly, if the
file TELIXOUT.XLT exists at start-up, it is assumed to be the default
outgoing translate table, and loaded.
3.13 Chat Mode
──────────────────────────────────────────────────────────────────────
Normally while using Telix with a remote host, your characters are not
echoed by Telix. When you type a character, it is sent to the remote
host, which checks it and then sends it back to you, and only then is
it printed on your screen. However if two users want to chat with each
other this becomes a problem, because each user's software expects the
other side to echo the characters back, and since it doesn't, nothing
is printed. Telix has a special Chat Mode to deal with this.
When you press Alt-Y Telix enters Chat Mode. Any characters you type
are printed on your screen immediately, without having to be echoed by
the other side. As well, it takes only a Carriage Return to advance to
a new line, a Line Feed character is not needed immediately af-
terwards. Telix also splits the streams of text. Any characters you
type are displayed on the bottom half of the screen, while the char-
Telix v3.22 Program Features 18
acters coming from the remote side are displayed on the top half of
the screen. When you wish to exit Chat Mode, press the Esc key.
3.14 Clear Screen
──────────────────────────────────────────────────────────────────────
To clear the screen press Alt-C. The screen will be cleared to the de-
fault colors, and the cursor will be placed in the upper left-hand
corner.
3.15 Local Echo
──────────────────────────────────────────────────────────────────────
Pressing Alt-E will toggle local echo on and off. If local echo is on,
characters you type are printed on the screen. If local echo is off
characters you type are not printed on the screen, they must be sent
back to you by the remote host to be printed by the screen. Most hosts
are set up so that local echo should be off; they will do the echoing.
This is called a full duplex host. Often however when talking to an-
other user, or when talking to a half duplex host, local echo must be
turned on to see the characters you type.
3.16 Add Line Feeds
──────────────────────────────────────────────────────────────────────
When a line of characters is received from a remote system, it is usu-
ally terminated by a Carriage Return followed by a Line Feed charac-
ter. If the Line Feed character is missing lines will overwrite each
other. If this seems to be happening when you are connected to a re-
mote host then you must make Telix add Line Feeds to each incoming
Carriage Return. Pressing Shift-Tab will toggle the adding of Line-
Feed characters. If this option is on, every time a Carriage Return is
received, a Line Feed is added immediately after it.
3.17 Break Signal
──────────────────────────────────────────────────────────────────────
Some hosts require the use of a special modem signal called a Break
signal, to do certain tasks like end transmissions. To make Telix send
a Break signal to the remote host press Ctrl-End.
3.18 DOORWAY Mode
──────────────────────────────────────────────────────────────────────
Pressing Alt-= while in Terminal Mode will toggle DOORWAY mode on/off.
DOORWAY mode is used by the DOORWAY utility by Dudley Marshall, and
several other applications. While in DOORWAY mode, when a key is
pressed Telix simply sends its raw scan code out the serial port, as
returned by the PC's BIOS keyboard function. Note that since for any
Telix v3.22 Program Features 19
key except Alt-=, Telix just sends the value to the serial port, you
must first switch out of DOORWAY mode to perform any Telix function.
3.19 Miscellaneous Functions
──────────────────────────────────────────────────────────────────────
Pressing Alt-M while in Terminal Mode will cause Telix to display the
Misc. Functions menu

3.19.2 Setting the Screen Size
The third through fifth options of the Misc. Functions Menu deal with
setting the screen size (height). These options are valid only on EGA
and/or VGA systems. Note that a standard EGA system can switch only
between 25 and 43 lines, and can not handle 50. Note that some VGA
cards can switch only between 25 and 50 lines, and can not handle 43.
Trying to use one of these options on a system not equipped with an
EGA or VGA video card is not allowed.
Telix v3.22 The Dialing Directory 21
4. THE DIALING DIRECTORY
Telix allows you to keep telephone numbers in files called dialing di-
rectories. A dialing directory is variable sized and can hold from 1
to 1000 entries. Besides the number, many other fields of information
are stored, such as the communications parameters needed to talk to
the service. All the fields are described below. The default dialing
directory file is called TELIX.FON, but you can have as many di-
rectories as you want and load them as needed.
To access the dialing directory press Alt-D while in terminal mode. A
small window will appear, asking you to enter the entries to dial or
to press Return to see the dialing directory. For the moment just
press Return. This first window is simply a very quick way to dial
your most commonly called numbers. Once you have pressed Return the
dialing directory will appear.
4.1 The Display
──────────────────────────────────────────────────────────────────────
Most of the screen is taken up by a window showing 15 (or more, de-
pending on the screen mode) of the possible 1000 entries in the dial-
ing directory. On the bottom of the screen is a menu of options, shown
here:
Dial List Toggle Find Manual Redial Add Edit Clear Unmark
Other
This menu works in a similar manner to the other menus found in Telix,
as described in the section 'Using Telix Menus'. In addition, since
dialing is such a common function, if any numeric key is pressed, it
is assumed that the 'List' function is wanted and this number is car-
ried over as the first digit entered for that function. At the same
time you may view the dialing directory. To scroll through the direc-
tory one entry at a time, use the Up and Down arrow keys. Use PgUp to
go back one page, and PgDn to go forward one page. Press Home to go to
the beginning of the directory, and End to go to the end of the di-
rectory. It should be emphasized that whenever the line 'Scroll with
Up, Down, Home, End, PgUp, and PgDn' is displayed, you may scroll
through the directory.
For each entry, many items are stored. All the fields can not be dis-
played at the same time; you may toggle which fields are shown on the
screen by selecting the Toggle command. Each entry contains informa-
tion under the following headers:
Name
The name of the remote service (i.e., Compuserve, Genie, Telix
Software Support BBS, etc.).
Telix v3.22 The Dialing Directory 22
Number
The phone number which Telix should dial to reach the remote ser-
vice.
Line Format
The communication parameters (such as baud rate, parity, etc.)
needed to talk to this service.
Script
A script file may be linked to each entry in the dialing direc-
tory. When Telix connects to this service, that script file is
then run, and may for example automatically log-on, entering your
name and password as needed, for greater convenience and speed.
LastCall
The date of the last successful call you made to this remote ser-
vice.
Total
The total number of successful calls you've made to this number.
Terminal
The terminal Telix should start emulating when a connection has
been reached to this number.
P (Protocol)
The first letter of the protocol which should be set as the de-
fault if a connection is reached to this number.
E (Echo)
Whether local echo should be on or off when a connection is
reached with this number.
L (Add Line Feeds)
This controls whether the Add Line Feeds setting should be on or
off when a connection is reached with this number.
H (Strip High Bit)
Whether Telix will strip the high (most significant) bit of in-
coming characters in terminal mode.
Telix v3.22 The Dialing Directory 23
BD (Backspace Destructive)
Whether a received backspace sequence is destructive (that is, if
the character backspaced over should also be erased).
BK (Backspace Key Value)
What value the Backspace key sends, either Backspace, or Del.
DP (Dialing Prefix Number)
This (advanced) setting is used to tell Telix what Dialing Prefix
to use when dialing this entry. One use for it is to turn on or
off MNP (error correcting) support in modems, to avoid delays
when the number called does not support it anyway.
Password
This field may hold a password for the remote service represented
by this entry. The password may be used by a script file to auto-
matically perform a log-on operation. Please note that this field
is not encrypted, so if security is a problem, do not store your
passwords in the dialing directory!
4.2 Editing an Entry
──────────────────────────────────────────────────────────────────────
To edit the currently highlighted dialing directory entry select Edit
from the dialing directory menu. A window will appear with the old
contents of the entry. You may edit each field, starting with the
first (name). To leave the contents of a filed as-is, press Enter. You
may move up and down in the list of fields by using the Tab and Shift-
Tab keys. Pressing Esc one or more times will get you out of the edit
window without any changes being made.
Once all the fields have been edited, Telix will ask you if the Last
Call and Total Calls fields should be cleared. Answer Yes or No as
needed. Telix will then ask for confirmation before writing any
changes to disk.
4.3 Adding Entries
──────────────────────────────────────────────────────────────────────
To add a blank entry to the end of the dialing directory, select 'Add
from the dialing directory menu. A dialing directory may hold up to
1000 entries.
Telix v3.22 The Dialing Directory 24
4.4 Clearing Entries
──────────────────────────────────────────────────────────────────────
To clear an entry or a range of entries select Clear from the dialing
directory menu. Telix will ask you to select the range of entries to
clear, by moving the highlight bar and pressing Enter. After confirm-
ing your choice, Telix will clear the selected entries back to empty
entries.
4.5 Finding an Entry
──────────────────────────────────────────────────────────────────────
To search for a particular entry in the dialing directory select Find
from the dialing directory menu. You will be asked to give the string
to search for. If Telix finds the entry with that string in it, that
entry will be highlighted. If while searching for the string Telix
reaches the end of the directory, it will wrap around to the beginning
and continue the search. If the string still can not be found Telix
will say 'Sorry, string not found'. If you want to search for the same
string as last time, just press Return when asked for the search
string.
4.6 Dialing
──────────────────────────────────────────────────────────────────────
Telix allows you to dial a group of dialing directory entries repeat-
edly until a connection is established, or you abort the attempt. Se-
lecting the Dial function from the dialing directory menu will make
Telix commence dialing in sequence all the currently marked entries.
You may also dial a user-entered list of entries, by selecting the
List function from the dialing directory menu. Telix will ask you to
enter up to 10 entries to dial in sequence (to make List dialing even
more convenient, you may also select the List function by pressing a
numeric key while in the dialing directory menu; this number is then
carried over and entered as the first digit in the string you are
asked to enter). While you are entering the list of entries to dial
you may also scroll through the directory as described above. If you
specify more than one entry to dial, each should be separated by a
space.
Sometimes you may want to dial a number that is not in the dialing di-
rectory. To do this select the Manual option of the dialing directory
menu, which stands for 'manual dial'. You will be asked to enter a
number to be sent to the modem. Whatever you supply will be sent out
exactly as is, except for Long Distance codes (see below), which are
still valid.
Telix v3.22 The Dialing Directory 25
4.6.1 Long Distance Codes
A Long Distance code is an advanced dialing option which adds some
flexibility. There are four Long Distance code characters: !, @, $,
and +, which when encountered while dialing expand to user-defined
strings (see section below on revising Long distance codes).
If Telix is dialing a number from a dialing directory entry, and one
of the Long Distance code characters is encountered in the number,
Telix will instead send whatever string has been assigned to that
code. For example, a dialing directory entry could contain the phone
number '!967-1111'. If the string '9,,' was assigned to the ! LD code
character, Telix when dialing this entry would first send the 9 fol-
lowed by the commas, and then send the rest of the digits.
LD codes may also be used with the List dial function. When you place
one of them in front of or behind an entry number to dial, it will be
expanded to a string. For example you could have the exclamation sign
'!', be expanded to '9,', or any string you specify. You may place up
to 3 Long Distances codes in front and one Long Distance code after
each entry number. For example, specifying the entry '+21!' would send
the string for the '+' Long Distance code, followed by the number from
entry 21, followed by the string for Long Distance code '!'. The
string
10 +15 20!
entered at the prompt would dial entry 10, then entry 15 with a Long
Distance code in front of it, and finally entry number 20, with a Long
Distance code after it. These numbers are redialed repeatedly until a
connection is reached. To learn about the redial window see the Redial
function below.
4.7 Other Functions
──────────────────────────────────────────────────────────────────────
Selecting Other from the dialing directory menu will present a menu of
secondary functions, dealing with the deletion or insertion of entries
in the dialing directory, with revising Long Distance Codes, and with
the handling of dialing directories (Telix allows you to have as many
dialing directories as needed and switch among them at will).
4.7.1 Inserting Blank Entries
To insert blank entries in the dialing directory, select Insert from
the dialing directory Other menu. Entries will be inserted at the cur-
rent position of the highlight bar. Telix will ask how many entries to
insert and will ask for confirmation before proceeding.
Telix v3.22 The Dialing Directory 26
4.7.2 Deleting Entries
To delete an entry or a range of entries in the dialing directory se-
lect the Delete option from the dialing directory Other menu. The
range to delete is selected by moving the highlight bar. After con-
firming your choice, the entries will be deleted and any following en-
tries will move up to where the deleted entries were.
4.7.3 Revising Long Distance Codes
To revise the Long Distance codes, select the option called Edit_LD
from the dialing directory Other menu. There are four Long Distance
code characters: ! @ - +. As described in the section on dialing, when
you place one of them in front of or behind a number to dial, it will
be expanded to a string. After selecting this option you will be shown
a menu of the available long distance codes. Selecting an LD Code will
let you modify the text currently assigned to it. After you have made
your changes, you must save them to disk with the Save Changes option,
if you want to use them every time you run Telix.
4.7.4 Creating a Dialing Directory
To create a blank dialing directory (which can later be modified), se-
lect the option called Create from the dialing directory screen's
Other menu. Telix will ask you for the name the new directory should
use. Any legal DOS filename is suitable, and there is no default ex-
tension. Telix will then create the blank directory on disk. The cur-
rent dialing directory is not be affected and will stay in memory.
4.7.5 Loading a Dialing directory
To load another dialing directory select the Load option form the di-
aling directory screen's Other menu. Telix will ask for the name of
the new directory and then load it into memory. Telix assumes a de-
fault extension of .FON, so if the directory you want to load does not
have one, include a period at the end (e.g., TELIX.) The new
directory becomes the default directory for the rest of the session or
until you load another one.
4.7.6 Printing the Dialing directory
Selecting the Print option from the dialing directory screen's Other
menu allows you to print out the current dialing directory, to the
printer, the serial port, or any device or disk file. Telix will ask
you for the device or file to print to. Enter the name or press Return
to use the PRN device (printer). Since these are DOS devices, Telix
has no way of knowing, for example, things such as whether or not your
printer is online. So if Telix seems to lock-up here, make sure your
printer is on and it is set to online.
Telix v3.22 The Dialing Directory 27
4.8 Automatic Queue Redial
──────────────────────────────────────────────────────────────────────
When Telix has one or more numbers to dial, it redials repeatedly un-
til a connection is made. To keep you informed of the status of the
redial Telix displays a status window, and alerts you when a connec-
tion is established. The status window is similar to the figure below.
╒═╡ Redial ╞═════════════════════════════════════════════════╕
│ │
│ Redial started at 20:15:33 Press: T to change dial time │
│ Attempt #10 20:19:27 D to delete from list │
│ │
│ This attempt: Dialing My Favorite BBS ... 22 │
│ number: 967-1111 │
│ Last Attempt: Busy │
│ │
│ Press Space to cycle to next number, Esc to exit. │
╘════════════════════════════════════════════════════════════╛
Information included in the status window is the time redial was
started, the time the current attempt was started, the status of the
last attempt, the status of the current attempt, and a countdown timer
for the current attempt.
If you are dialing all the marked entries with the dialing directory
Dial command, when a connection is reached, the mark is taken off the
entry connected to, so that when you later select the Dial function
again, only the remaining entries are dialed. If you are dialing a
list of entries selected with the List dialing directory command, when
a connection is established the entry connected to is taken out of the
list, so that when you later select the Redial command from the dial-
ing directory or the Alt-Q command from terminal mode, only the re-
maining entries will be shown.
While redialing, you have the option of changing the time that Telix
waits for a connection, and also the option of deleting a number from
the list to dial, by pressing 'T' and 'D' respectively.
Normally, when a connection has been reached, Telix sounds an alarm to
alert you of this. If a script file is linked to the entry however,
the alarm is skipped so that the script may immediately proceed. It is
thus the responsibility of the linked script to alert the user of the
fact that a connection has been reached.
Pressing Alt-Q while in the terminal mode or selecting 'Redial last'
from the dialing directory menu will allow you to redial one or more
numbers that you entered previously using the 'List' command, so that
you do not have to re-enter them. You will be shown the list and asked
to edit it until you are satisfied, and then to press Return.
Telix v3.22 The Dialing Directory 28
4.9 The Quick Dial Bar
──────────────────────────────────────────────────────────────────────
You may have noticed that after you press Alt-D an inverse bar is dis-
played on the bottom of the screen, asking you to select the entries
to dial or press Return to see the Dialing directory. Up to now, you
have just pressed Return to go on to the Dialing Directory, but this
bar is a quick way to dial commonly called directory entries whose
numbers you have memorized. You may enter a list of entries to dial
just as if you had used the List command of the dialing directory
menu. This saves the dialing directory from having to be displayed on
the screen if you already know the entry or entries you want to dial.
The Quick Dial Bar can also be used to dial a number manually. To do
this just preface the number with an 'm'. For example, 'm967-1111'
would dial 967-1111, just as if you had used the Manual dial option of
the Dialing Directory. Either lowercase or uppercase 'm' is accepted.
The use of the Quick Dial Bar may be disabled via the Configuration
Menu.
Telix v3.22 File Transfers 29
5. FILE TRANSFERS
Sending files from one computer to another is one of the most useful
things you can do with your modem. Telix supports a full assortment of
the most popular file transfer protocols, including Xmodem, Xmodem-1k,
Xmodem-1k-g, Zmodem, Compuserve Quick B, Kermit, Ymodem, Ymodem-g,
SEAlink, Telink, Modem7, and ASCII. Telix's file transfers are very
fast, surpassing most programs in speed by a respectable margin. All
file transfers use a 10 Kbyte buffer, and full error detection is
standard.
Telix allows you to define up to five external protocols, which are
completely integrated into the file transfer menus. When you select
one of these protocols, Telix executes a DOS batch file or Telix
script file, which must then call the appropriate external driver for
the protocol. In this way, you may add virtually any file transfer
protocol to Telix. Adding external protocols is defined in the section
on the Configuration Menu.
5.1 Downloading (Receiving) Files
──────────────────────────────────────────────────────────────────────
To start downloading (receiving) a file from a remote host, you must
usually inform the remote host of the files that you want it to send
to you before starting the transfer on the Telix side. You must then
start the download on the Telix side. Pressing the Alt-R key will dis-
play a menu asking which file transfer protocol you would like to use:
╒═╡ Download file ╞═╕
│ │
│ Which Protocol? │
│ │
│ ASCII │
│ CIS Quick B │
│ Kermit │
│ Modem7 │
│ SEAlink │
│ Telink │

│ 1k-Xmodem │
│ G-1k-Xmodem │
│ Ymodem (Batch) │
│ YmodEm-g │
│ Zmodem │
│ Quit │
│ │
╘═══════════════════╛
If any external protocols are defined, they are also shown as part of
the menu.
Telix v3.22 File Transfers 30
If you have selected Xmodem, Xmodem-1k, Xmodem-1k-g, or ASCII, as the
protocol, Telix will ask you for the filename to save the file to.
Telix always watches what you type while online, and will often know
the name of the file you want to transfer, in which case this name
will be displayed and all you have to do to accept it is press Return.
Any legal DOS filename is valid, including a path. If the filename you
supply already exists, Telix will ask you to confirm your choice or
give another filename. If you select any other protocol, the remote
sender of the file will supply the name to save the file to. If you
have entered a download directory name in the Configuration Menu,
Telix will automatically save download files there if you don't spec-
ify another path. Telix has automatic incoming file protection. If the
name is supplied by the host and exists already the file is renamed by
using numerals in the extension, as needed.
During the transfer, a full status window is displayed showing the
elapsed time, the number of bytes received, and an approximate Charac-
ter Per Second rating, which can give an idea of the effective speed
of the transfer. Batch protocols will also display the expected file
size and file transfer time. For ASCII transfers, a status window is
not displayed, only a single status line at the top of the screen. To
abort a file transfer at any time press the Escape key.
5.2 Uploading (Sending) Files
──────────────────────────────────────────────────────────────────────
To start uploading (sending) a file to a remote host you must also
usually inform the host of the file you will be sending it before
starting the upload on the Telix end. To start the upload on the Telix
end press the Alt-S key. This will display a menu asking you which
file transfer protocol you want to use to send the file. After you
have selected the protocol, you will be asked for the file(s) to send
by a dialog box:

Telix v3.22 File Transfers 31
This is a complex dialog, and deserves more detailed attention. Once
mastered, this dialog will greatly streamline the uploading process.
There are four separate windows in the dialog. The selected dialog
will have a bar at the top, highlighting the name of the window. You
may move from one window to the next using Tab and Shift-Tab to move
forward or backward, respectively. In any window, pressing Up-Arrow
or Down-Arrow move the highlight bar in that direction if possible.
Pressing F10 closes the dialog and uploads the files selected.
Tagged Files: This window contains a list of all of the files Telix
is to upload. It will be blank when the dialog first
appears. You may select files to be included in this
list as described below. Files already listed may be
removed from this window by highlighting the file and
pressing Enter or Space.
Path/Dir: This window is where the currently displayed upload
path will be displayed. You may add files to the
Tagged Files List from this window by typing in the
exact name of the file. You may use the wildcard
characters ? and * (see your DOS manual, for more
information about wildcard characters). You may change
the currently displayed upload path by entering a new
path here.
Filelist: This window contains the files in the currently
displayed upload path. This window may contain a
maximum of approximately 700 files. Files listed in
this window may be added to the Tagged Files List by
highlighting the file and pressing Enter or Space. If
you wish to add or remove all files in this window
(both those on and off the screen) to or from the
Tagged File List, you may do so with F3 and F4
respectively.
Drives This window contains a list of all available disks in
your system, except for floppy drives. Users of
removable disks such as Bernoulli boxes may have to
load a cartridge to upload a file. You may change the
drive on which the Filelist is read from by selecting a
new drive from this window.
During the file transfer, a full status window is displayed, unless
you are using ASCII protocol, in which case only a status line is dis-
played. Information shown is the expected time the transfer will take,
the time remaining, the number of bytes to send, the number of bytes
left, and an approximate Character Per Second rating, which can give
an idea of the effective speed of the transfer. To abort a transfer at
any time press the Escape key.
Telix v3.22 File Transfers 32
5.3 File Transfer Protocols
──────────────────────────────────────────────────────────────────────
Xmodem - Xmodem is often called the "lowest common denominator"
protocol, and is the father protocol of many others. Xmodem sends
files in blocks of 128 characters at a time. When the receiving com-
puter is satisfied that the block has arrived intact, it signals so
and waits for the next block. Error checking is a checksum or a more
sophisticated Cyclic Redundancy Check. Telix supports both and will
automatically use the right one. During a download, Telix will attempt
to use the CRC, but will switch to checksum if it seems the host does
not support CRC. The Xmodem protocol also needs a setup of no parity,
8 data bits, and 1 stop bit. If your communications parameters are
different from these when you start an Xmodem transfer, Telix will
switch to the required setup for the transfer, and back to the origi-
nal setup after it is finished. In the Configuration Menu, you may en-
abled Relaxed Xmodem timing. This is for use with remote services that
can not tolerate strict timing during Xmodem transfers.
Xmodem-1k - This is a small variation of the above that uses blocks
that are 1 Kilobyte (1024 bytes) in size. This protocol is still mis-
takenly called 'Ymodem' by many programs, but people are gradually
moving over to the proper name.
Xmodem-1k-g - This is a variation of the above that is meant for er-
ror-free channels such as error correcting modems or null modem cable
links between two computers. It achieves great speed by sending blocks
one after another without waiting for acknowledgment from the re-
ceiver. Because of this however, it can not re-send blocks in case of
errors (and thus the need for an error-free link). If an error is de-
tected by the receiver, the transfer is aborted. This protocol is
still mistakenly called 'Ymodem-g' by many programs, but people are
gradually moving over to the proper name.
Compuserve Quick B - This protocol is used only on the Compuserve
Information Service. It is quite fast and specially suited for the
networks used in accessing CIS, which have large turnaround delays.
This is a windowed protocol, which basically means that unless errors
are detected, data is being sent at all times. A CIS Quick B transfer
is totally controlled by Compuserve. After telling CIS what file(s) to
send, the user does nothing. Telix, in terminal mode, then detects the
command from CIS which tells it to start the transfer (note that CIS
Quick B transfer must be enabled in the Configuration Menu, or they
will not work).
Zmodem - This advanced protocol is very fast and very reliable, and
offers many features. It can arguably called the most popular protocol
in use today. Zmodem can transfer a group of files in one batch, and
keeps the exact file sizes and dates. Zmodem can detect and recover
from errors quickly, and can resume an interrupted transfer at a later
time (this feature, called Crash Recovery, may be toggled in the
'Protocol options' page of the Configuration Menu). Zmodem is also
very well suited for satellite links and packet switched networks.
Telix v3.22 File Transfers 33
SEAlink - SEAlink is an advanced version of Xmodem developed by Sys-
tem Enhancement Associates. It is a sliding window protocol SEAlink
is 15 to 25 percent faster than regular Xmodem. SEAlink passes a
file's name, size, and date when transferring it, and can be used to
send more than one file at a time.
ASCII - in an ASCII transfer, it is as if the sender is actually
typing the characters and the receiver is just recording them. There
is no form of error detection used. Usually only ASCII files can be
sent in this way, as binary files contain characters which would foul-
up the screen.
Ymodem - This protocol is a variation on Xmodem, which allows for
multiple files to be sent per transfer. While transferring files, it
keeps the correct name, size, and date, and may use 128 or 1024 byte
block sizes.
Ymodem-g - This protocol is a variation on the above, which achieves
very high transfer rates by sending blocks one after another without
waiting for acknowledgment. This however means than an error-free link
such as an error-correcting modem or null modem cable between two com-
puters is needed. If an error is detected by the receiver, the trans-
fer is aborted.
Telink - This protocol is mainly found on Fido BBS systems. It is
basically the Xmodem protocol using CRC checking with an extra block
sent ahead of the file telling its name, size, and date. This protocol
allows more than one file to be sent at a time.
Modem7 - Modem7 is a close cousin to Xmodem that passes the filename
before starting the transfer, thus taking away some of the user's
work. It is common on CP/M systems. This protocol allows more than one
file to be sent at a time.
Kermit - The Kermit protocol was developed to make it easier for
computers of different types to send files to each other. Almost any
computer using Kermit can be set up to send files to another computer
using Kermit (the same can be said of Zmodem however). Various options
in the Kermit protocol implemented in Telix can be tailored to the
user's needs in the Configuration Menu, option 'Kermit transfers'.
This implementation of Kermit does not include a Kermit "server" func-
tion, and cannot use "SEND", "GET", or other server commands.
5.4 Which One to Use
──────────────────────────────────────────────────────────────────────
Telix supports a large number of built in file transfer protocols. To
this can be added external protocols. It can get confusing to decide
which one to use. When both sides of the connection only support one
protocol, then obviously that is the one to use, no matter what its
deficiencies. Otherwise some protocols are a better choice than oth-
ers. On Compuserve, CIS Quick B should be used. For most purposes,
Zmodem is the best all around protocol. It is very fast and very reli-
able. Ymodem-g and Xmodem-1k-g are slightly faster. However these two
Telix v3.22 File Transfers 34
protocols need an error-free link. After that, Ymodem, SEAlink, and
Xmodem-1k are quite fast and pretty reliable. The last choice would be
Xmodem and its close cousins Telink and Modem7. ASCII transfers are
suitable only for text files and do not perform any error detection or
correction, so they are to be avoided if possible.
Telix v3.22 Telix Configuration Menu 35
6. TELIX CONFIGURATION MENU
Telix has many features which can be customized. These include things
like the screen setup, the communications parameters, filenames and
paths, and many other items. The default values for these parameters
are stored in a file called TELIX.CNF, the configuration file. Telix
will automatically read this file upon starting up. The first time you
use Telix, this file is created for you with some standard default
values. Pressing Alt-O while in terminal mode brings up the Telix Con-
figuration Menu, which allows you to change all these default set-
tings.

╘════════════════════════════════╛
The first seven options are parameter screens, the last two deal with
leaving the Configuration Menu.
6.1 Screen and Color Settings
──────────────────────────────────────────────────────────────────────
This screen allows you to set various video related options. You will
be shown a menu listing the various parts of the screen displays (such
as menu foreground colors). If you pick one of these items you will be
allowed to scroll through the possible colors for it by using the ar-
row keys. When you have selected the right colors, press Enter. If you
want to leave the colors menu without selecting one press Esc.
Another setting on the Screen and Colors menu is the 'Screen write
mode'. If you pick this option you will be asked in which way you want
Telix to write to the screen. This depends on the video adapter pre-
sent in your system. The first option is a direct screen write. This
is the fastest mode, and should be used if you have a monochrome
adapter, an EGA adapter, or another video adapter that never gets
snow. The second option is a direct screen write with port checks.
Telix v3.22 Telix Configuration Menu 36
This method is slightly slower. You should use this method if you
screen gets snow on it or it flickers while executing the DOS 'dir'
command. One card with which you should use this is the color/graphics
adapter. Don't use this option if your video card doesn't need it, as
it may interfere with communications. The final method is a screen
write with BIOS calls. You should use this method with applications
like Topview or DoubleDOS. This method is quite slow however. Note
that you do not need this mode to run Telix under DESQview, since
Telix is DV aware.
Another setting on this menu is 'Default screen size'. This allows you
to pick an alternate default screen size of 80x43 or 80x50. Note that
these modes require an EGA or VGA card. Note also that many EGA cards
can not do 80x50, and some VGA cards can not do 80x43.
When you have finished picking the colors, select the 'Keep changes &
exit' option if you want to keep the color changes you have made, or
the 'exit' option if you want to discard them.
6.2 Terminal Options
──────────────────────────────────────────────────────────────────────
This screen contains settings related to Telix operation while in
terminal mode (with some extending to other areas of Telix). To select
a setting to change type the letter beside it. Telix will then allow
you to change the old setting. Press Esc at this point to exit without
changing anything. Options include:
A Default Communications Parameters
These include comm port, bps (baud) rate, data bits, parity, and
stop bits. Note that the current settings will not change, only
the defaults for the next time you load Telix. Alt-P changes the
current settings.
B Emulate Before Translation
Some European systems override characters used by many terminal
emulations to signal color changes and other items that don't
show up on the screen as characters. Normally a received
character is passed through the translation tables before being
examined to see if it is such a character. This option allows
the emulation to occur first, and then only translates those
characters not seen as emulation commands.
C Default Terminal Type
Allowable terminals are "TTY", "ANSI-BBS", "VT102", "VT52",
"ANSI", and "AVATAR". Note that the current terminal will not be
changed, only the terminal used the next time you run Telix.
Telix v3.22 Telix Configuration Menu 37
D Status Line
Telix allows a status line to be displayed at the top or bottom
of the screen. The status line shows some useful information.
Valid options are Top, Bottom or None. While in Terminal Mode the
status line may also easily be toggled on or off by pressing
Alt-8.
E Default Local Echo
This controls whether or not Telix should echo on the screen any
characters you type while in Terminal mode. This is usually off
for BBS use. Local echo on is often also called Half Duplex,
while local echo off is called Full Duplex.
F Add Line Feeds
This controls whether or not Telix should add line feeds to
incoming Carriage Returns characters while in terminal mode. If
you are connected to a remote system and lines are overwriting
each other, this should be on, otherwise it should be off.
G Strip High Bit
Telix can strip the high (most significant) bit from incoming
data bytes while in terminal mode. This is sometimes useful be-
cause it allows the high/parity bit of incoming text to be ig-
nored.
H Received Backspace Destructive
This setting controls how Telix treats incoming backspace charac-
ters. If backspace characters are destructive, Telix backs up
over the previous character and erases it, otherwise the existing
character is not erased.
I Backspace Key Character
Normally, Telix sends Backspace when the Backspace key is
pressed, and DEL when Ctrl-Backspace is pressed. This option al-
lows these settings to be swapped.
J XON/XOFF Software Flow Control
This controls whether or not Telix should use the XON/XOFF soft-
ware handshaking protocol while in terminal mode and during ASCII
file transfers. This should usually be on.
K CTS/RTS Hardware Handshaking
Hardware handshaking is used with high speed modems and null mo-
dem cable links to regulate the flow of data. If the modem sup-
ports Hardware handshaking this should be on. If a null modem ca-
Telix v3.22 Telix Configuration Menu 38
ble is being used and these signals are valid over the cable,
this should be on.
L DSR/DTR Hardware Handshaking
Hardware handshaking is used with high speed null modem cable
links to regulate the flow of data. If a null modem cable is be-
ing used and these signals are valid over the cable, this should
be on. Often a null modem cable will allow one type of hardware
handshaking to be used, but not the other.
M Compuserve Quick B Transfers
Compuserve Quick B file transfers are initiated by Compuserve,
which sends a few special characters (Ctrl-E and Ctrl-P). Telix,
upon detecting these characters while in terminal mode, starts
the transfer. If another Host is sending these characters and
causing problems, this option allows CIS Quick B recognition to
be turned off.
N Zmodem Auto-Downloads
Telix, while in Terminal Mode, can detect the packet from another
computer sending files using the Zmodem protocol, and automati-
cally begin a Zmodem download on the local end. This option al-
lows this feature to be disabled.
O Answerback string
Some systems require that the terminal program send an identifi-
cation string when an ENQ (Ctrl-E) character is received. You may
define such an 'answerback' string here. If this string is empty,
nothing is sent. As well, note that the answerback string is not
sent if Compuserve Quick B transfers are enabled (above), as
Ctrl-E is used as part of that protocol.
6.3 General Settings
──────────────────────────────────────────────────────────────────────
This screen allows you to change some general default settings, in-
cluding:
A Sound
If this is off Telix will not make ANY sounds.
B Alarm Sound
If this is off Telix will not make ANY alarm sounds, but will
still beep when it receives the bell code from the remote host,
unless the sound option is also off.
Telix v3.22 Telix Configuration Menu 39
C Keep Aborted Downloads
If this is on, Telix will keep files which were aborted during a
download. Otherwise Telix will delete these files.
D Show Free Space for Downloads
This setting controls whether or not Telix will display the free
space on the disk when you start a download. The option to turn
it off is provided because the free space display takes a few
seconds for large hard disks.
E Quick Dial Bar
When you press Alt-D to access the dialing directory, Telix nor-
mally first displays the Quick Dial Bar at the bottom of the
screen, which allows you dial entries without having to view the
dialing directory. If you would rather go directly to the dialing
directory when you press Alt-D, set this option to Off.
F Confirm Hang-Up
Setting this option to on will make Telix ask for confirmation
before hanging up, when Alt-H is pressed.
G Default Usage Log Setting
If this option is set to on, Telix will open the default Usage
Log (as specified on the Filenames and Paths screen) at program
start up. Otherwise the usage log must be manually turned on if
needed.
H Scroll-Back Buffer Size
This setting controls the size of the Telix Scroll-Back buffer
(in kilobytes). For changes to this setting to take effect you
must save the changes to disk and restart Telix.
I Capture File Buffer Size
This is the size of the disk buffer that Telix should use for the
Capture file when it is opened. Values from 0 to 4 Kilobytes are
allowed. A larger buffer size means the disk is accessed less of-
ten.
J Date Format
This is the format that Telix should use when displaying dates.
Allowed formats are MMDDYY, DDMMYY, and YYMMDD.
Telix v3.22 Telix Configuration Menu 40
K Date Separator Character
This is the character that Telix will print between parts of the
date when displaying a date. The default character is the hyphen
(-).
L Time Format
This is the format that Telix should use when displaying times.
Allowed formats are 12-hour and 24-hour.
M Time Separator Character
This is the character that Telix will print between parts of the
time when displaying a time. The default character is the colon
(:).
N Enhanced Keyboard Support
This option allows you to turn off Telix's support for the en-
hanced (101) keyboard. This should normally be left on, unless
there seems to be a keyboard problem.
O Shell: 16550 Buffer
This option allows you to specify whether the buffer on the
16550a comm chip should be left on or off during a DOS shell. If
it is installed in your PC, Telix normally recognizes and enables
the buffer on this chip at all times, for greater efficiency, but
there are still a few comm application that users might want to
run from the shell which can not handle the chip with the buffer
turned on.
P Shell: Swap to EMS/XMS/Disk
This option allows you to specify whether Telix will attempt to
remove most of itself from memory when executing DOS function
calls. The default is off for backwards compatibility, but most
users should be able to turn this on without problems.
6.4 Modem and Dialing settings
──────────────────────────────────────────────────────────────────────
This screen contains settings that Telix uses to control the modem and
its output. The default configuration that Telix comes with is set up
for Hayes compatible modems. These modems use the 'AT' command set. By
changing these settings Telix can work with almost any modem. The pa-
rameters are:
Telix v3.22 Telix Configuration Menu 41
A Modem Initialization String
This string will be sent to the modem when Telix first starts.
Different modems might need different strings. The default string
is set up for Hayes compatible modems. It is:
ATZ^M~~~AT S7=45 S0=0 V1 X4^M
where:
AT is the modem attention code
Z resets the modem to default state
^M sends the terminating Carriage Return character to
the modem.
~~~ pauses to give the modem time
AT is the modem attention code.
S7=45 makes the modem wait 45 seconds for a connection.
S0=0 turns off auto answer.
V1 makes the modem respond with words.
X4 makes the modem give extended result codes.
^M sends the terminating Carriage Return character to
the modem.
B Dialing Prefix 1
A Dialing prefix is what Telix sends to the modem when dialing,
before the number, for example, 'ATDT' for Hayes compatible
modems. There are three dialing prefixes allowed, and in the di-
aling directory you may chose which one to use for each entry.
One use for this is if your modem support MNP, to define two pre-
fixes which turn MNP support on and off, thus avoiding the delay
when you call a system that doesn't support MNP.
C Dialing prefix 2
D Dialing prefix 3
E Dialing Postfix
The string Telix should send after the number when dialing. On
Hayes compatible modems this is just a Carriage Return character,
'^M'.
F Connect String
The string which the modem sends upon establishing a connection.
e.g., 'CONNECT'
G No connect strings
Up to four strings which the modem sends when it has failed to
make a connection while dialing, for example 'NO CARRIER',
'BUSY', etc.
Telix v3.22 Telix Configuration Menu 42
H Hang-up string
This is the string Telix should send to the modem to make it hang
up. The default string works for Hayes compatible modems and is:
~~~+++~~~ATH0^M
where
~~~ pauses Telix for 1 1/2 secs.
+++ escapes the modem into command mode.
~~~ pauses Telix for 1 1/2 secs.
AT is the modem attention code.
H0 tells the modem to hang up.
^M sends the terminating Carriage Return character to
the modem.
Before sending this string to the modem Telix always tries to
hang-up the modem by a faster way that works with MOST modems.
This is done by dropping (turning off) a special signal called
the DTR (Data Terminal Ready) line on the RS-232 port. If drop-
ping the DTR makes the modem hang-up then the hang-up string is
not sent to the modem.
I Auto Answer String
This is the string that Telix should send to the modem upon
entering Host Mode. This string should allow the modem to
automatically pick up the phone when it rings, and initialize it
in any other ways that might be necessary.
J Dial Cancel String
The string Telix should send to the modem to cancel the current
dialing attempt. On most modems all that is necessary is a Car-
riage Return character, "^M".
K Dial Time
The amount of time Telix should wait for a connection while di-
aling. This should usually be set to be greater than the amount
of time the modem waits for the connection.
L Redial Pause
The number of seconds Telix should wait between attempts while
redialing.
M Auto Baud Detect
If this option is on and Telix dials a number, it will check the
modem connect message for a baud rate indication. If the baud is
different than was specified for the entry being dialed, Telix
Telix v3.22 Telix Configuration Menu 43
switches to the new baud rate. This option only works with Hayes
compatible modems. This option must not be enabled when you have
told the modem to maintain a constant or locked baud rate between
the computer and the modem, as is often done with high-speed, er-
ror correcting modems, or modems supporting MNP (e.g. USR HST,
Hayes V-Series, etc.).
6.5 Filenames and Path Settings
──────────────────────────────────────────────────────────────────────
This screen allows you to change several filename and pathname de-
faults, including:
A Download Directory
The disk directory in which Telix should save files which are
downloaded (received). The user can override this by giving a
full pathname when prompted.
B Upload Directory
The disk directory where Telix should look for files to be up-
loaded. The user can override this by giving a full filename when
prompted.
C Script Directory
The directory in which Telix should look for script files when
trying to execute them. The user can override this by using a
full pathname in front of the filename when specifying it.
D Default Capture File
The default name Telix should use when opening the capture file.
The user can override this.
E Default Usage Log
The default name Telix should use when opening the Usage Log. The
user can override this.
F Directory Program
The name of the disk directory program the Telix should run when
you select the 'Files directory' command. If you do not specify a
program here Telix will use an internal routine that also dis-
plays the amount of time it will take to transfer each file in
the directory. An example of a program you could specify here is
'dir/p', which would use the DOS dir command with pauses at each
page full, to display the directory.
Telix v3.22 Telix Configuration Menu 44
G Screen Image File
The file that Telix should save screen images (generated with the
Alt-I command) to. the default name is TELIX.MSG.
H Editor Pathname
The name of your editor, including the extension of the name
(EXE, COM, or .BAT for batch files), for example, C:\EDITOR.COM.
The indicated file must either be in the current directory, in a
directory included in the DOS Path, or the name must include the
full path. You need to set this parameter only if you want to run
your editor using the Alt-A, Run Editor command.
6.6 ASCII Transfers
──────────────────────────────────────────────────────────────────────
This screen allows you to customize Telix ASCII file transfers to your
needs, so that Telix may work with almost any system. Available set-
tings are:
A Strip High Bit
If this parameter is on, the high (most significant) bit of each
character sent for uploads, or received for downloads, is
stripped. This can be used to ignore parity. On the other hand,
the upper 128 characters in the IBM extended ASCII character set
are then converted to the lower value.
B Remote Abort Character
This is the character which when received during an ASCII upload
or download, is taken to mean that the remote end wants to abort
the transfer. One possible value might be 24 (Ctrl-X).
C Local Echo
If this is on, Telix will echo characters locally while upload-
ing. This should normally be off.
D Expand Blank Lines
If this is on, when Telix is sending a file and it encounters a
blank line, it will add a space to that line. This is very useful
for systems that assume a blank line means "end of file", or for
uploading a message on most bulletin boards.
E Pace Character
This is the ASCII value of the character that Telix should wait
for before sending each line. If this value is 0, Telix will not
wait for any character.
Telix v3.22 Telix Configuration Menu 45
F Line Pacing
This is the amount of time (in 1/10 seconds), that Telix should
wait before sending each line. This delay is often not necessary,
but for some bbs's for example, it's vital.
G Character Pacing
This is the time delay (in milliseconds) that Telix should wait
between each character. As the PC's hardware clock does not have
enough resolution, this is a software loop based delay. There-
fore, a value of 1 here will delay a 4.77 MHz XT approximately 1
millisecond, and faster PCs for a proportionally smaller time pe-
riod.
H Upload CR Translation
This is what Telix should do with Carriage Return chars when up-
loading ASCII files. The three options are to do nothing, to
strip them, or to add a Line Feed character afterwards.
I Upload LF Translation
This is what Telix should do with Line Feed characters when up-
loading ASCII files. The three options are to do nothing, to
strip them, or to add a Carriage Return before each.
J Download CR Translation
This is exactly the same as setting E (above), but applies when
downloading ASCII files.
K Download LF Translation
This is exactly the same as setting F (above), but applies when
downloading ASCII files.
6.7 Protocol options
──────────────────────────────────────────────────────────────────────
This screen allows you to configure external protocols, as well as a
few other settings.
An external protocol is simply a file transfer protocol that is imple-
mented outside of Telix. You specify the name of the protocol, the key
used to select it on the file transfer menu, and define how it is to
be called. You may optionally define a string which will trigger an
automatic download much like the auto zmodem transfer capability built
into Telix. Items 'A' through 'E' are the definitions for the five
external protocols allowed. When you select a definition to edit,
Telix will ask a series of questions:
Telix v3.22 Telix Configuration Menu 46
Key
The key that should be pressed to select this protocol when the
file transfer menu is displayed.
Protocol Name
The name Telix will display on the file transfer menu for this
protocol.
Upload Filename
This is the name of the DOS batch file or Telix script file to
call when the user selects an upload using this protocol. If this
filename begins with an "@" symbol, Telix will create an ASCII
text file "FILELIST" containing the list of specified or tagged
files, one file per line. Many external protocols can accept
such a file as a parameter, and thus limits on the number of
files that can be passed on a DOS command line may be
circumvented.
Download filename
This is the name of the DOS batch file or Telix script file to
call when the user selects a download using this protocol.
BAT or Script
This controls whether the above two filenames are DOS batch files
or Telix script files.
DL Name
This option controls whether or not Telix should ask for the name
of the file when performing a download using this protocol. In
many protocols, the sender passes the name of the file(s) to the
receiver, so Telix shouldn't ask for the download name.
Trigger String
This option is a place to enter a string which when received is
indicative of a file being received by the protocol. Telix can
thus automatically detect an incoming file and move to download
it without need of your intervention. This string must be
consistent, unique, and positively identify the occurance of an
incoming file. Check your external protocol documentation to
determine if the protocol supports a trigger string. This
option should be left blank if there is no trigger available for
the protocol.
See the Appendix titled External Protocols for information about what
information is passed to the batch or script files when an external
transfer is selected.
Telix v3.22 Telix Configuration Menu 47
Other settings on this page are:
F File Transfer Disk Buffer Size
This allows you to set the size of the disk buffer used by Telix
during file transfers from 1k to 10k (kilobytes) in size. A
larger value is more efficient with floppy disk systems, while a
smaller value can get around problems with disk controllers or
Extended memory use on some hard-disk systems.
G Relaxed Xmodem Timing
This option controls whether or not Telix should use relaxed tim-
ing when performing an Xmodem transfer. When calling some ser-
vices, this option must be turned on because they can not toler-
ate strict timing.
H Filename Guessing
This option controls Telix's use of filename guessing. When you
selected a file transfer to be performed, telix can often guess
the name of the file to be transferred, based on your past
keystrokes. This option may be turned off here. As well, you may
specify that Telix gives only guesses which it is almost certain
are filenames, or gives its 'Best try', which may include guesses
with extra characters which are not necessarily part of the file-
name.
I Zmodem Receive Crash Recovery
When an aborted Zmodem transfer must be resumed, this option
should be turned on. While this option is on, if a file being
downloaded using Zmodem already exists on the disk (and is
shorter than the file the sender has), Telix will tell the sender
to send only the bytes needed to complete the file. This option
should be used with care. The possibility exists that a file with
the same name but different contents exists on each system, in
which case you do not want only some of the data transferred.
J Zmodem Send Crash Recovery
When this option is on, during a Zmodem upload of files, Telix
will try to tell the sender to resume aborted transfers. This op-
tion should be used with care, as some systems do not support
crash recovery, and will behave unpredictably.
K Allow Zmodem 32 bit CRCs
Real speed freaks may turn off the use of 32 bit CRC error check-
ing (still quite reliable 16 bit CRCs are used instead), to get
on the order of a quarter to a half of a percent speed increase
in Zmodem transfers.
Telix v3.22 Telix Configuration Menu 48
L Zmodem Window Size
Zmodem normally sends data in streaming mode, never pausing un-
less the other side requests a re-send due to an error being de-
tected. In some environments, a pause for acknowledgments can be
more efficient. The window size (in kilobytes) is the maximum
amount of data the protocol should seed before waiting for a re-
ply. A value of 0 indicates streaming mode should be used.
M Zmodem File Type
This option allows you to specify whether the file being trans-
ferred with the Zmodem protocol is Binary, ASCII, or Either. Bi-
nary means that Telix will make sure no end-of-line conversion is
done on files received or sent. ASCII means that on a download,
as long as the other side doesn't override this, Telix will as-
sume the file being received is a text file and will make sure
the end of each line has a Carriage Return followed by a Line
Feed, by adding the CR if the file has only LFs at the end of
each line. An ASCII setting when sending will make Telix tell the
other system to do end-of-line conversion, although the other
system may override this. Finally, a setting of Either (the de-
fault), will make Telix assume the file is binary, unless the
other system indicates otherwise. DO NOT use a setting of 'ASCII'
for file that are not ASCII text files, as binary files will be
corrupted by this option.
6.8 Kermit Transfers
──────────────────────────────────────────────────────────────────────
This screen allows you to configure Telix's implementation of the Ker-
mit protocol to your needs. The options will not be described here,
due to the fact that the Kermit protocol is relatively complicated,
and if you must change one of these parameters, you should generally
already know what it means.
6.9 Comm Port Setup
──────────────────────────────────────────────────────────────────────
This screen allows you to configure/define the communications ports.
Telix supports definitions for 8 comm ports. By default, the first
four comm ports are defined to the standards for COM1 through COM4.
The last four comm ports are by default duplicates of COM1. For each
port you may define the base address (in hexadecimal) of that port, as
well as the interrupt request number (irq) to use. Unless you are ab-
solutely sure about your information, do not modify these values!
Wrong values could cause unexpected and possibly disruptive results.
Telix v3.22 Telix Configuration Menu 49
6.10 Saving Changes and Leaving
──────────────────────────────────────────────────────────────────────
Any modified settings can be saved to the configuration file (so that
they will be remembered when you next use Telix) by selecting the
Write Setup to Disk option. If you want to keep any changes just for
the current session, then exit the Configuration Menu using the Exit
option.
Telix v3.22 Terminal Emulation 51
7. TERMINAL EMULATION
A video display terminal is basically a relatively dumb computer which
is linked up to another computer (over a cable or modem link) and dis-
plays what that computer sends to it. A mainframe or mini computer has
a large amount of processing power and can drive a number of terminals
at the same time.
There are many different terminal types. Each one follows its own
codes for controlling how information is displayed on the screen. For
example, there are sequences to clear the screen, move the cursor,
scroll the display, and so on. Most terminals also have special keys
which send special sequences back to the main computer.
Telix can emulate several terminals. While in terminal mode, you may
change the terminal type Telix is currently emulating by pressing Alt-
T. The default terminal can also be set in the 'Terminal settings'
page of the Configuration Menu. Following are the choices Telix of-
fers:
7.1 TTY
──────────────────────────────────────────────────────────────────────
A TTY (Teletype) terminal is very stupid. It basically displays all
the values it receives, except for about 5 or 6 Control codes (such as
Carriage Return), which move the cursor and ring the bell. Telix does
not have any special key definitions for this terminal type.
7.2 ANSI-BBS
──────────────────────────────────────────────────────────────────────
This is a subset of the real ANSI terminal type defined by the Ameri-
can National Standards Institute. Many BBS programs, when told to do
so, can send sequences supported by this terminal to make screen dis-
play more interesting and colorful. This emulation supports some known
bugs in the DOS ANSI.SYS driver that are not part of the ANSI standard
per se.
The ANSI.KEY file contains definitions for the arrow keys, and is au-
tomatically read when this terminal is selected. These definitions are
supported by some full screen editors, for example.
7.3 ANSI
──────────────────────────────────────────────────────────────────────
This is the real ANSI terminal type defined by the American National
Standards Institute. Many BBS programs, when told to do so, can send
sequences supported by this terminal to make screen display more in-
Telix v3.22 Terminal Emulation 52
teresting and colorful. This conforms to the ANSI committee defini-
tions of ANSI.
7.4 VT102
──────────────────────────────────────────────────────────────────────
The DEC VT102 terminal is one of the most popular (and most emulated)
terminals in existence. It was developed by Digital Equipment Corpora-
tion. The VT102 terminal has a large number of functions. Telix sup-
ports all of these except for 132 column mode and double height mode.
As well, Telix only emulates double width mode, by adding a space af-
ter every character.
Telix fully supports both normal and application cursor mode in VT em-
ulation. The VT102 keyboard layout used by Telix is stored in the
VT102.KEY file, which is automatically read by Telix when VT102 termi-
nal emulation is selected. Once Telix has loaded this into memory, the
definitions can be edited through the use of the Alt-K
(Keyboard/macros) function.
The default keyboard layout is best suited for the (newer) 101-key
style keyboards with separate arrow and numeric keypads, and functions
keys across the top. In this layout, press F1 to F4 to simulate the
VT's PF1 to PF4. With the NumLock key down, the PC's numeric keypad
will simulate the VT's numeric keypad, while the arrow keys on the
PC's numeric keypad (with the NumLock up) or the separate arrow keypad
(at all times) will simulate the VT's arrow keys. Note that Telix will
only recognize the separate arrow keypad if you turn on the 'Enhanced
Keyboard' setting on the General Options screen of the Configuration
Menu.
Another keyboard layout is available that is possibly better suited to
older style keyboards with function keys on on the left side and no
separate arrow keypad and numeric keypad. To make use of this alter-
nate layout, while at the DOS prompt type:
ren VT102.KEY VT102101.KEY
ren VT102OLD.KEY VT102.KEY
This layout is similar to one used by many comm programs, in which the
normal function keys (F1-F10) represent the left side of the VT's nu-
meric keypad, while the shifted function keys (Shift-F1 - Shift-F10)
represent the right side, as follows:
Telix v3.22 Terminal Emulation 53
Telix function Keys DEC VT102 Keypad

│ 0 │ │ . │ │ R │ │ 0 │ │ . │ │ R │
└───────────┘ └────┘ └────┘ └───────────┘ └────┘ └────┘
The arrow keys are also defined to send the proper sequences.
7.5 VT52
──────────────────────────────────────────────────────────────────────
The DEC VT52 is another relatively common terminal type, that is con-
siderably simple than the VT102. Telix's key definitions for the VT52
are stored in the VT52.KEY file.
Telix v3.22 Using Script Files 55
8. USING SCRIPT FILES
8.1 The Scripting Languages
──────────────────────────────────────────────────────────────────────
Telix has an incredibly powerful built-in 'script' or command lan-
guage, called SALT (Script Application Language for Telix). In the
simplest terms, a script file is a sequence of commands for Telix to
follow, written using a certain format. Script files can do many use-
ful things like automatically logging on to a host, setting up special
parameters, performing unattended file transfers, and many other
tasks. A script file can be linked to a dialing directory entry so
that it is run automatically when that entry is connected to, and sup-
plies the needed logon information.
Like any real programming language, SALT has a large number of fea-
tures. Because of this, programming in SALT is not easy for the begin-
ner who has no knowledge of any programming concepts. However SALT
scripts can be used to different degrees. The advanced user can pro-
gram complex applications, while even a novice can modify the sample
scripts include with Telix, and run scripts supplied by others.
For advanced users, a separate 100+ page manual describes SALT and its
syntax. The rest of this section describes how to create, run and
compile the various forms of scripts. All forms of scripts must be
compiled by one of the two compilers (CS.EXE or CSS.EXE) and all
scripts are executed with the ALT-G command.
8.2 SALT
──────────────────────────────────────────────────────────────────────
Before a SALT script can be used, it must be 'compiled'. The CS.EXE
program included with Telix takes the ASCII 'source' scripts that the
user writes, and compiles or converts them to a form that is easier
for Telix to process, usually takes less space, and loads more
quickly. SALT scripts may actually use any name. However in standard
practice the extension 'SLT' is used for SALT source scripts, and the
same name with the extension 'SLC' is used for the compiled version.
If you have an already compiled SALT script (ending with the extension
'SLC' (for example, the QDHOST.SLC Host Mode script file), it is very
easy to execute. While in terminal mode, press Alt-G. Telix will ask
for the name of the script file to run. If you supply no extension,
'SLC' is assumed. If a special directory where script files are to be
found has been defined, Telix will look there for script files, unless
a path is given. To define this script directory use the Telix Con-
figuration Menu. Telix will then load the script file and follow its
instructions. To abort a script while it is executing, press the Esc
key. Sometimes you may have to press Esc twice, the first time to
abort the current function, and the second time to abort the script
itself.
Telix v3.22 Using Script Files 56
You may have used your text editor to modify one of the sample scripts
included with Telix (most simply require inserting your name in a
clearly marked location near the top). You now need to compile the
script file. To do this, the CS.EXE program is used. While at the DOS
prompt, type 'CS', followed by a space and the name of the script file
you want to compile (the extension 'SLT' is assumed if none is given).
CS will scan through the source file and produce the compiled version,
using the same base name but the extension 'SLC'. If a syntax error is
discovered while compiling the script file, CS will report it and
abort. In that case the error should be fixed and CS run again. From
within Telix, you may quickly run CS either by using the DOS Command
function (Alt-V), or from the DOS Shell (Alt-J).
Remember, every time you make a change to the source file, you must
re-compile it, otherwise Telix will still run the old compiled ver-
sion. This sounds tedious, but in practice once a script is developed
it doesn't change very often.
8.3 SIMPLE
──────────────────────────────────────────────────────────────────────
For those users not comfortable in a structured programming
environment, Telix provides a Salt IMPLEmentation, or SIMPLE scripting
language. SIMPLE is a non-structured language that is converted to
the more complex SALT for the user prior to actually compiling it.
SIMPLE scripts need to be compiled with the CSS.EXE program. While at
the DOS prompt, type 'CSS', followed by a space and the name of the
SIMPLE script file you want to compile. The extension .SIM is assumed
if none is given. CSS will scan through the source file and produce a
compiled .SLC file. If a syntax error is discovered while compiling
the script, CSS will report it and abort.
Simple requires that the CS.EXE SALT compiler reside in the DOS path.
A complete listing of all SIMPLE scripting commands and structures is
available in SIMPLE.DOC or in the printed manual.
8.4 Learning a Script
──────────────────────────────────────────────────────────────────────
Some operations you will perform in Telix are highly repetitive, such
as logging onto an online service. The user name, password, and
other information is always entered in the same order, the same way,
every time you call. You can use the Script Learn function to create
an automatic log-on script to do this for you each call.
To learn a sequence of responses to prompts, toggle the learn mode on
from telix Terminal mode by pressing ALT-9. Enter the name of the
script to learn when prompted. .SLT is assumed to be the filename
extension if one is not given.
Telix will record your responses to the various prompts of the online
service until learning mode is turned off with ALT-9 again. When
turned off, Telix saves the learned script. Remember, the learned
script must be compiled prior to use.
Telix v3.22 Using Script Files 57
It is important while learning a script to remember to wait for the
complete prompt to be displayed before responding. Unpredictable
results can be exhibited if a fast typist or a user familiar with a
service types ahead of the prompts.
Learned scripts, while useful, are not always completely accurate, and
may not work without editing. If the prompt being responded to
contains information that can vary (such as the number of minutes left
online), then the .SLT file may need to be edited prior to being
compiled. An example is the prompt on the Telix support BBS, which
usually reads much like the following:
(4 used, 86 left) Main Board Command?
If there are not exactly 86 minutes remaining on your next call, a
learned script containing this prompt will not function properly.
The line in the learned script:
waitfor("(4 used, 86 left) Main Board Command", 30);
should thus be edited to read:
waitfor("Main Board Command", 30)
for proper operation of the learned script.
Script learning is only available in registered versions of Telix.
Telix v3.22 Host Mode 59
9. HOST MODE
Telix allows you to set up your computer as a remote host, so that
others may call your system and perform operations like transferring
files and chatting. In short it is like having a small BBS on your
system, without all the setup work. Telix provides two such host
modes, both implemented in Telix's powerful SALT script language.
QDHOST is a 'Quick and Dirty' host mode containing the basic features
of a remote host, including password security and remote shells to
DOS. A more powerful host, HOSTPLUS, is also provided, offering the
functionality of a full-featured BBS with multiple message bases and
file areas, multiple security levels and individual password security
and user levels. The operation of HOSTPLUS is described in
HOSTPLUS.DOC, or in a separate section of the printed documentation.
There are a few requirements to running Host Mode. Your modem must be
able to pick up the phone when it rings. Your modem must not be set to
override (always keep on) the Carrier Detect signal it supplies, so
that Telix can tell when it is connected to a caller. Telix must also
be able to hang up the modem by dropping (turning off) the DTR line on
the RS-232 port. If one of these requirements is not met you probably
cannot run QDHost.
To run the QDHOST script, press Alt-G while in Terminal mode, and then
enter 'QDHOST' as the script file name. The script 'QDHOST' will then
be run. Several Host Mode configuration settings are kept in a file
called 'QDHOST.CNF'. The first time you run the Host Mode script, it
will not find this file, and automatically run the host Mode configu-
ration script 'QDCONFIG', which will created the needed file and allow
you to change the default values. At any time in the future, you
should run QDCONFIG when you need to configure the Host Mode. QDCONFIG
will present you with the following parameters:
A Level One Access Password
The password that callers must successfully enter to be admitted
to the Host Mode and have Level One access. Level one access
allows only files contained in the specified QDCONFIG download
directory to be downloaded.
B Level Two Access Password
This is the password that callers must successfully enter to be
admitted to QDHOST and have Level Two (Sysop) access. Level two
access allows the caller to download any file on the system by
giving the path.
C DOS Shell Password
This is the password that users of QDHOST have to enter to use
the Remote DOS Shell option.
Telix v3.22 Host Mode 60
D Shut Down Host Mode Password
This is the password that callers must enter to shut down QDHOST,
when they press Ctrl-Z.
E Host Download Directory
Level 1 access callers will only be able to download (have Telix
send them) files that are in this directory. As well, the 'F'iles
command will show them only the contents of this directory. Do
not under any circumstances define this directory to the same
name as the directory you run Telix in. If you did that, callers
could download the QDHOST configuration file, which is stored
there, and see your passwords. Level 2 access callers may specify
any download path, but this is the default.
F Host Upload Directory
Level 1 access callers will only be able to upload (send to
Telix) files into this directory. Level 2 access callers can
specify any path, but files will go here by default.
G Connection Type
This can be either 'Modem' or 'Direct'. Use 'Modem' if your host
system is being accessed through a modem, or 'Direct' if two
computers are hard-wired. This stops Telix from trying to ini-
tialize a non-existent modem. or trying to determine the caller's
baud.
H Locked Modem Rate
For error correcting modems, QDHOST needs to know if the DTE rate
(the speed Telix communicates with your modem) is constant from
call to call, no matter what speed the user calls in at. Set this
value to the fixed DTE rate (usually 9600 for 2400MNP modems, and
19,200 or 38,400 for 9600+ baud modems). If your modem is not er-
ror correcting or you are unsure what the value should be, set
this value to zero.
There is one other important parameter which must be properly set for
QDHOST operation. This is the Auto Answer string, which is defined in
the 'Modem and dialing' page of the Configuration Menu. This string is
sent to the modem when Telix enters QDHOST, and should make the modem
able to pick up the phone when it rings. The default string is set up
for Hayes compatible modems. It is:
AT X1 S0=1^M
where
AT is the modem attention code.
Telix v3.22 Host Mode 61
X1 tells the modem to reply with extended result
codes. This means the modem indicates the caller's
baud rate.
S0=1 tells the modem to answer after one ring.
^M sends the terminating Carriage Return character.
There are two optional text files which are displayed to callers if
they exist, called LOGO.MSG, and WELCOME.MSG. They are described be-
low.
Once QDHOST has been configured, it can actually be run. Telix will
make a note in the QDHOST audit file QDHOST.LOG and then will imme-
diately send the Host Mode init string to the modem. Telix then waits
for a caller. While in QDHOST on the local side, the user can always
press Esc to exit Host Mode, or End to terminate the current caller.
He can also enter commands for the remote caller, so that a novice
caller can be helped along by the host operator. Also, at any time,
the current caller will be automatically terminated if there is inac-
tivity for five minutes, or the connection is lost. This is all noted
in the host audit file. If the caller has only access level one, ref-
erences to other disk directories than the ones defined in QDCONFIG
are ignored, and all operations take place in those directories. As
well, Telix protects your files from being accidentally overwritten by
the caller.
When the Carrier Detect signal turns on Telix knows a caller is on-
line. At this point Telix will try to determine the caller's baud
rate. Most Hayes compatible modems can be initialized to send the
string 'CONNECT baud' where baud is the baud rate of the caller, when
they sense a connection. If Telix sees this string it will switch to
the appropriate baud. If this string is not received within a few sec-
onds of the connection, Telix will leave the baud rate at whatever it
was. Also, it should be mentioned that Telix can not determine the
caller's other settings like parity, data bits, and stop bits. These
must already be matching Telix's settings.
At this point, if the file LOGO.MSG exists in the Telix directory, it
is displayed to the caller. It should basically identify the system.
Then Telix will ask the caller for his/her name. The name must be at
least five letters long and is only used when indicating the caller in
the Host Mode audit file. If a password has been defined Telix will
ask the caller for it. The caller has three tries to complete the
password. All password attempts, successful or failed, are written to
the Host audit file. If the caller enters the Level One access pass-
word, he may manipulate only the disk directories defined in QDCONFIG.
Any other directories can not be accessed. If he enters the Level Two
access password, the caller may use full pathnames in all file speci-
fications. The level 2 password should only be kept for yourself or
those you completely trust, as a Level 2 caller can access any files
on your system.
If there is a file called WELCOME.MSG in the Telix directory, it is
then shown to the caller. This file can contain further identification
Telix v3.22 Host Mode 62
or news, that you only want valid callers to see. After each 23 lines
the caller is prompted to press any key to continue. As well, the
caller may press Ctrl-S to pause at any time, and Ctrl-C or Ctrl-K to
abort the listing. After the WELCOME.MSG file is displayed the caller
is presented with a menu of options:
Files Type Upload Download Shell Chat Goodbye ?
The action to be taken is selected by entering its first letter. Case
does not matter. As mentioned already, the host operator is free to
enter any keystrokes for the caller.
The Files option allows the caller to list the files in the current
disk directory. The caller must press a key after each screen. The
output is not echoed on the local screen. If the caller has access
level two s/he is prompted for a filespec, which may include the * and
? wildcard characters (see your DOS manual), so that the contents of
other directories than the 'Host download dir' may be listed.
The Type option allows the caller to view any ASCII file in the Host
Download Directory, or in any directory for access Level 2 callers.
The same format and commands are available during this command as for
the displaying of the optional message file WELCOME.MSG.
The Upload option allows the caller to send a file to the host. The
caller is shown the following menu (here slightly compressed so it
could fit):
Modem7 SEAlink Xmodem 1k-Xmodem G-1k-Xmodem Ymodem Ymodem-g
Which protocol?
and should select the appropriate protocol by its first letter (or 'E'
for Ymodem-g). If appropriate the caller is also asked for the file-
name. The transfer is then initiated. Level 1 callers may only upload
files into the 'Host Upload Directory' defined with QDCONFIG.
The Download command allows a caller to receive a file from the host.
The caller must select the protocol as described above, and then must
tell Telix the file(s) to send. The transfer is then initiated. Level
1 access callers may only download files from the 'Host Download Di-
rectory' defined with QDCONFIG.
The Shell command is a very powerful but also very dangerous command.
It allows the caller to run a DOS shell on your system, except that
the caller receives the output, and the caller enters the keystrokes.
This command is basically similar to entering 'CTTY COMx' at the DOS
prompt. The remote side has complete control of your system. This is
obviously very dangerous, as the caller can format disks, delete
files, or perform any other operation. To provide security, a password
must be entered to use the remote DOS shell. Be very careful of whom
you give this password to, as they can do anything they want with your
system. As well, don't leave it at the default that Telix comes with.
There are a few limitations in the remote DOS shell. The caller will
see program output only if the programs use standard DOS output. Pro-
Telix v3.22 Host Mode 63
grams that write directly to the video screen will work, but will not
be seen by the remote caller. As well, programs that use non-DOS meth-
ods of getting keystrokes will not receive the callers keystrokes. Fi-
nally, under some systems, if the caller presses Backspace at the DOS
prompt when the current line is empty, DOS will hang on the Host ma-
chine. As these are functions of DOS, there is nothing that can be
done about these limitations.
A potentially powerful feature of the shell function is the ability to
override the use of CTTY and use your own redirector, such as Dudley
Marshall's DOORWAY.EXE. Do not confuse DOORWAY.EXE with Telix's
DOORWAY mode. If the file RSHELL.BAT exists in the same as
QDHOST.SLC, QDHost will run that batch file instead of using CTTY, and
return to QDHOST when it is complete. DOORWAY.EXE is an excellent
alternative to CTTY when both users need to see the screen, or when
programs that write directly to the screen (such as Word Perfect) must
be run from remote. The following is a sample RSHELL.BAT for use with
the Doorway program:
DOORWAY com1 /M:100 /O: /V:D^U /C:DOS
Note that the com port must specified by number in the batch file.
However, CTTY only supports COM1 and COM2, while Doorway can support
up to COM4. If you receive the message that you cannot shell due to
DOS limitations, DOORWAY.EXE can be used as an alternative. The
latest version of DOORWAY including complete DOORWAY.EXE documentation
is available on the Telix support BBS.
The Chat command allows the caller to chat with the host operator.
When the caller presses 'C' the host operator is paged for 20 seconds.
Press the Space bar to chat with the caller, or any other key not to.
Accepting the chat will place you in Chat Mode, exactly as if you had
used the Alt-Y command. The caller's keystrokes are echoed back to
him/her however, so that he/she can see them.
Finally, the Goodbye command allows the caller to log off the host. An
entry noting the time and date is made in the host audit file, and
Telix then waits for a new caller.
The caller may also use one other command that is not displayed in the
menu. This is to shut down QDHost Mode. If the caller presses Ctrl-Z
and successfully enters the shut down Host password defined in the
Configuration Menu, the QDHost Mode is shut down and Telix returns to
whatever it was doing before QDHost was initiated.

Telix v3.22 Questions and Answers 67
11. TROUBLESHOOTING
Problem:
Telix and the modem do not seem to be able to detect busy signals.
Solution:
Some modems (especially older 1200 bps units) do not have the capabil-
ity to detect busy signals. Assuming yours does, you'll still probably
have to edit the default modem Init String. The X1 that Telix uses in
the string to be compatible with all modems does not enable busy de-
tection in most modems. Try a value like X3, X4, or higher.
Problem:
When the QDHost Mode script is run Telix always thinks that a caller
is online and immediately asks for the caller's name or Telix always
says that a Hang-up operation failed even when it did in fact success-
fully hang-up the modem.
Solution:
Your modem is almost certainly overriding the true state of the Car-
rier Detect signal. This is the factory default on most modems, but
should be disabled. For proper operation, Telix needs to see this sig-
nal on when connected to another computer, and off when not. If your
modem has dip switches, as do most 1200 bps units and all US Robotics
external Couriers, switch number 6 usually controls this and must be
in the up position. If your modem does not seem to have any dip
switches (look carefully, sometimes the front needs to be popped off),
it is probably controlled solely by software commands, as are most
2400 bps units. Just a few examples of these are the Hayes 2400, ATI
2400etc., GVC 2400, and many others. For these modems, adding &C1 in
the modem Init String (before the final ^M (Carriage Return is a good
spot)) will configure the modem properly.
Problem:
When trying to use a multi-tasking system like MS Windows, Topview, or
DoubleDOS, with Telix in the background, window displays bleed through
to the active partition.
Solution:
In the Telix Configuration Menu, select the 'Screen and colors set-
tings' option, then select as the Screen Write Mode, 'BIOS calls used
for writes'. Screen updating will be slower but will not bleed
through.
Telix v3.22 Questions and Answers 68
Problem:
When redialing Telix does not seem to know when a connection has been
reached.
Solution:
Telix knows when a connection has been reached in one of two ways:
when it receives a Connect string from your modem, or when the Carrier
Detect signal turns on (if it was off). Make sure that the Connect
string is properly defined in the Configuration Menu, or that your mo-
dem does turn on the Carrier Detect signal regardless of whether or
not there is a connection.
Problem:
Telix doesn't work with a certain modem.
Solution:
Telix is set by default to use the Hayes 'AT' modem command standard.
There are modems that are not Hayes compatible however, and use other
commands to dial, hang up, and perform other tasks. Make sure that if
your modem is not Hayes compatible Telix has been properly configured
to its commands.
Problem:
When trying to use the DOS Shell, or another function that uses DOS,
Telix warns that it can not find a file called COMMAND.COM, and aborts
the function.
Solution:
The file COMMAND.COM is the DOS command interpreter. Telix must be
able to find it to use many DOS functions. The location of COMMAND.COM
is stored in an environment variable (explained in your DOS manual)
called COMSPEC. COMSPEC is set at boot-up, but if you boot of a floppy
and then change to another floppy or a hard disk, it will not point to
the right place anymore. In short, make sure that COMSPEC always
points to the location of COMMAND.COM, or that COMMAND.COM is in the
current directory.
Problem:
When calling some systems, especially large ones such as Compuserve or
the Source, all incoming characters look like garbage.
Solution:
The communications parameters are probably wrong. Most of these sys-
tems need a setting of Even parity, 7 data bits, and 1 stop bit. This
is different from the normal standard of N81 used for most bulletin
boards.
Telix v3.22 Questions and Answers 69
Problem:
When running Telix, it reaches the "initializing modem" screen but
won't go any further.
Solution:
Unfortunately, the solution here is not simple, and requires some
knowledge of hardware. If you are not comfortable with configuring or
jumpering your hardware, please contact a qualified computer consul-
tant or service shop. The problem is likely that two devices in the
computer wish to use the same part of the computer at the same time
(called using the same interrupt). This will be the case with internal
modems on COM3 or COM4, when you have other serial devices (mice,
Sound Blaster cards, network interface cards, or other interrupt
driven devices). By default, COM1 shares an interrupt with COM3, and
COM2 shares with COM4. Only one device may use an interrupt at a time.
You should try to place your internal modem on an unused interrupt
(IRQ 5 is free in most AT or 386 class systems), and then tell Telix
under the Configuration menu that COM3 or COM4 now uses IRQ5.
Problem:
During transfers with a high speed modem, many CRC and/or timeout er-
rors occur.
Solution:
First ensure that CTS/RTS hardware flow control is enabled and that
DSR/DTR hardware flow control is disabled both in Telix under the Con-
figuration menus in the Terminal Options section and in your modem
(refer to your modem manual for instructions on setting up your modem
properly, or use the MODEMCFG.EXE program). If this fails, it may sim-
ply be hardware limitations. Sometimes such hardware limitations can
be circumvented by running Telix with the /D parameter.
Many high-speed modems, especially in a multitasking (Windows,
DESQview, TopView, etc.) environment or on XT or slower AT-class ma-
chines are simply too fast for the hardware, and may need some help to
prevent lost characters. A UART (Universal Asynchronous Receiver-
Transmitter) is a chip found on every serial card or internal modems.
Most serial cards or internal modems come stock with 8250 or 16450
chips that are not rated for high speed modems. A replacement chip
called the NS16550AN will likely eliminate such problems.
Problem:
When I run Telix from my menu program it tells me "Unable to find/open
ANSI.KEY" and goes back to the menu program.
Solution:
ANSI.KEY is a file required for Telix operation, but due to the menu
not changing to the Telix directory, Telix cannot find this file.
Telix v3.22 Questions and Answers 70
Telix expects to find all of it's system files in the current
directory or in the directory pointed to by the TELIX environment
variable.
An environment variable is a setting that DOS can look at (or other
programs, like Telix) to find out certain information it needs.
By placing the command:
SET TELIX=C:\TELIX
in your AUTOEXEC.BAT (modified for your own Telix path, of course)
Telix will then know to look there for all of it's files if they are
not in the current directory. There should be no spaces in the command
as above, other than between SET and TELIX.
Problem:
I have call waiting on my phone line and whenever someone calls me
while I'm online, I get disconnected.
Solution:
Call waiting is usually disableable on outgoing calls only. Contact
your operator or phone company to determine if it can be disabled, and
if so, what the codes are in your area. In many areas, it is *70, so
we will use that as an example.
First, check your modem manual to insure that the modem is capable of
dialing all the necessary characters like * or #. If not, you will
have to do this by hand on your phone before each call, or ask the
operator if there are alternatives (often 1170 will work, but it takes
longer).
If your modem CAN dial the needed characters, or you are told of a
suitable substitute, edit the dialing prefixes under Telix's Config:
ALT-O - Modem and Dialing - Options B,C,D
Insert after each "DT" (or DP if on pulse dialing) the appropriate
call waiting cancel string. Note that often a comma is necessary as
a pause to get a second dial tone. Once this is saved permanently to
your Telix config ("W"rite setup to disk), you're set. Most often
these will be:
ATDT*70,
Problem:
I have a new 14,400 bps modem, but Telix doesn't support 14,400 as a
speed option.
Solution:
Telix v3.22 Questions and Answers 71
This is one of the great misconceptions about high speed modems, so
you're not along in wondering this. Let me try to detail why it
doesn't matter, and at the same time give you a bit of an idea what's
going on behind the scenes when you call another modem...
The link to get from your computer to the other computer looks much
like this:
Telix <--> Your modem <--> Their modem <--> Their computer
DTE rate DCE rate DTE rate
38,400 14,400 57,600
As you can see, it is really a series of three links; one between
your computer and your modem, one between the two modems, and one
between their modem and their computer. What might surprise you is
that each of these three rates can be, and often are, completely
different, as above. So you know, DCE stands for Data Communications
Equipment (i.e. a modem to modem link) and DTE is Data Terminal
Equipment (i.e. terminal to modem link). You are not concerned with
the final link, the remote DTE rate. That is up to the remote site,
and does not matter at all to you. Once the data leaves your modem,
and is received by theirs, it is out of your hands.
Your modem likely has either MNP-5 or v.42bis data compression built
in. For transferring non-.ZIP files, these modems can be extremely
efficient in compressing the data before sending it -- sometimes as
much as 4 times compression (25% of the original size).
If the modems can take 1000 characters from Telix, and then turn it
into perhaps as little as 250 characters with compression, your modem
still transmits at 14,400 and would need 1000 characters from the comm
program to transmit a mere 250 characters. In order to keep the DCE
link flowing with data non-stop, Telix has to send data to your modem
at 4 times the speed the modem is talking to the other modem (in the
best case, which almost never happens). Thus, the DTE (Telix to modem
rate) must be higher than the DCE (modem to modem rate) by a good
margin, or the modems will sit idle frequently, waiting for the comm
program to supply it with enough data. Since you have no way of
knowing how much the data will be compressed, or at what speeds the
two modems will actually connect up at, you should ALWAYS leave the
DTE rate on your end (the link between Telix and your modem as
specified in the Telix configuration) locked in, or fixed, at that
high rate that can accommodate the most efficient case, since that
most efficient case can occur at any time.
That's why you're always advised by MODEMCFG.EXE to set the comm
program's speed, as well as all dialing directory entries (no matter
how fast the board actually is), to a speed higher than the 9,600 or
14,400 you really have. Typically, you'll be told to use 19,200 or
38,400 (nowadays, typically 38,400, and even some will say 57,600).
But the important thing is, that speed is constant. Your DTE
(program to modem rate) always stays the same, so that when that most
efficient case comes along, you're ready.
Telix v3.22 Questions and Answers 72
Problem:
When trying to transfer a file, telix just sits there saying "Waiting
to send." or "Waiting to receive" but nothing ever happens.
Solution:
When a user is downloading, the other system is by definition
uploading to him. BOTH systems must know exactly what is happening at
every given moment, and this is especially true at the beginning of
the transfer.
First the downloader must tell the remote system (the one to be
downloaded FROM) that s/he requests a download. On most systems, this
is accomplished with the "D"ownload command.
The sending system will then ask the downloader to choose a protocol.
You may choose any one that Telix supports, but we recommend Zmodem if
it is available, and 1K-Xmodem (sometimes labeled Ymodem) if Zmodem is
not available. In any case, the important thing to remember is that
BOTH the sender and the receiver must be using the same protocol, and
it must be agreed upon in advance.
Perhaps before choosing a protocol, you will be asked what files you
wish to download. Then the system may tell you that it is ready to
send the files. If you have selected Zmodem, and have Zmodem auto-
downloads on in Telix (the default) you should not have to do anything
more. Telix will sense the Zmodem transfer coming and go into ZModem
receive mode. Sometimes this will appear as "garbage" like an up
arrow, a bunch of asterisks, and numbers like 0's and 8's. This is a
signal to start!
The most important thing to remember when downloading is that first
you have to tell the other system what to send and how to send it, and
let it get started. As soon as the other system starts, you
generally have about 30 to 60 seconds to start your receive with the
SAME protocol. It is crucial that both sides know that a transfer is
taking place. You cannot start yours early, or the other side will
never send the file.
Thus, don't hit Alt-R (or PgDn) until you are *sure* the other side is
ready to send, and ready for you to tell it that you are ready to
receive (ALT-R does this automatically).
Problem:
When trying to compile a script I get the message "Unable to open
file" even though I know the script is present.
Solution:
Some OEM versions of DOS 2.11 (notably, the Tandy DOS burned into the
1000 HX) are incompatible with the compiler used in these cases. This
does not apply to Telix itself.
Telix v3.22 Questions and Answers 73
It is highly recommended that you upgrade your DOS if possible. For
users with the DOS burned into the ROM of the machine, you may boot
from a system floppy of a higher DOS system to compile scripts.
Problem:
When I start a download, the transfer window disappears very fast,
with a message that looks like "Unable to open file", and no transfer
takes place.
Solution:
Telix expects to be able to open a new file in the subdirectory you
have defined for the Download Directory under ALT-O/Filenames and
Paths. If this subdirectory does not exist, that will cause this
message to appear:
"Unable to open file!"
This is a sure sign that you need to check your configuration in this
area, and either create the defined subdirectory from the DOS prompt
with the MKDIR command, or to change the configuration under ALT-O/F
to reflect the location of an existing path.
Problem:
When I transfer a file, sometimes letters flash in the lower right
corner of the transfer window.
Solution:
This is completely normal, and signifies a "flow" control, or a signal
to Telix or the modem to slow down or stop momentarily. It signifies
that things are in good working order.
Problem:
How do I telix to operate reliably under Microsoft Windows?
Solution:
TELIX.PIF included with Telix is a Program Information File for
Windows that should allow best operation of Telix under Microsoft
Windows. Windows doesn't offer the best of communications handlers,
though, and for best communications results under Windows, we
recommend a Windows-based program. deltaComm is currently programming
a Windows comm program expected to be released in the first half of
1994.
Problem:
My modem requires compatible software to use the MNP features of my
modem, or it says it needs RPI compatible software. Is Telix
compatible in this way?
Telix v3.22 Questions and Answers 74
Solution:
No, it is not, and there is little likelihood that we will support RPI
or software MNP in the near or distant future. RPI is an attempt by
Rockwell and the modem manufacturers to create a cheaper modem (by
about $5) by pushing off some of the hardware implementation into
software. We disagree with this for the sole reason that software
cannot be as efficient as hardware (esp. when coprocessed), and that
these functions truly belong on the hardware for efficiency and speed.
Most comm developers we know feel the same way and without our support
the manufacturers will have to go back to putting these functions on
the hardware -- where they belong.
Our recommendation is to take the modem back to the place of purchase,
and don't leave until you get a REAL MNP/v.42bis modem at exactly the
same price, because what you bought was not what you thought you did,
and the only way the industry will stop these shenanigans is for the
ones being taken advantage of to stand up for themselves and do
something about it.
Problem:
We have our modems on a network and we need a network version of Telix
in order to access them. Does Telix have network support built in?
Solution:
Networking a comm program, or using a modem across the network as a
resource requires two things.
1) The network must be NETBIOS compliant.
2) The comm program must use the BIOS (Int-14) for comm routines.
Telix normally bypasses the slower BIOS and writes directly to the
comm port for speed considerations, making it incompatible with
networks.
However, we have developed a version of Telix which uses the Int-14
calls, and it is now available as a separate product. please call
our sales staff for more information about Telix for Networks.
Problem:
When I run QDHost it says "Either the upload or download directory as
defined in the Host config does not exist" and then aborts. What
now?
Solution:
If you receive this message when running the QDHost mode then you need
to do the following:
Telix v3.22 Questions and Answers 75
From Telix Terminal mode (the blank screen that you are at after the
opening screen goes away), press ALT-G, and type "QDCONFIG". The
QDCONFIG.SLC script must exist in the same directory as QDHOST (i.e.
in the script directory as defined under ALT-O/Filenames).
You will then see a menu that pops up something like this:
A: Level 1 password : pass1
B: Level 2 password : pass2
C: Remote Shell password : shell
D: Shut down host pass : shut
E: Host download directory: C:\TELIX\HSTFILES\ <------
F: Host upload directory : C:\TELIX\HSTFILES\ <------
G: Connection type : Modem
H: Modem locked at >= 9600: No
I: Exit without saving changes.
J: Exit and save changes to disk.
The indicated lines are the ones that need to be changed. You can
either Exit without saving and then do MKDIR with the above paths:
MKDIR C:\TELIX\HSTFILES
or, better, is to change options E and F above to paths that you know
already exist (NEVER set these equal to your Telix subdirectory!), and
then "Exit and Save Changes to Disk". For more information concerning
DOS paths, please consult your DOS manual.
Problem:
When calling from our office we have to use a credit card number, but
the whole number won't fit in the dialing directory. How can
telephone credit cards be used with Telix?
Solution:
The MODEM is going to be your bottleneck here. Most modems cannot take
as many characters at once as a comm program can send out. The vast
majority of modems have a 40 character command string limit, which
must include the <ENTER> at the end, and the ATDT (or ATDP) at the
beginning. Spaces, dashes, and any directives for MNP and such in the
dialing prefixes also count.
Telix can, with the use of long distance codes, send much more than
this, but the modem will not likely respond to this, since anything
past 40 characters is simply ignored (and this includes your <ENTER>
at the end).
Many long distance companies have gone to 13 character card codes to
protect you against fraud, and this is a good idea. However, it does
limit you via your modem (again, Telix is not the limitation here).
Telix v3.22 Questions and Answers 76
In the number you wish to dial, rather than making the number in the
directory read: "1-919-481-9399"
Save space (it's STILL tight) and make it read: "1-919-481-9399!"
The exclamation point tells Telix to append the contents of that code,
and the code can be edited to include any sequence you wish, under
Alt-D/Other/Edit LD codes.
Problem:
Telix seems to be grossly optimistic when estimating the length of
time it will take to transfer a file. Its usually about four times
slower than Telix thinks it will be. Why is this?
Solution:
Previous versions of Telix merely estimated transfers based on the
speed that Telix dialed at (the DTE), even though this could be up to
four times greater than the actual connect speed.
Telix 3.22 now makes its best attempt to read the actual connect speed
(DCE), but needs a little cooperation from the modem. Telix cannot
determine the DCE on its own -- it must rely on the modem to report
it.
Telix must accept the rate that the modem offers -- it has no way to
"validate" it. The best way to demonstrate this is to dial a number
without using the dialing directory. Type ATDT and the number, and
press Enter. Watch for the first string that displays. It will be
something like:
CONNECT 14400/ARQ/V42BIS/LAP-M
If you have a vanilla 2400:
CONNECT 2400
If the dialing directory had been used, Telix would have read the
connect rate as 14400 in the first case and 2400 in the second.
(Telix reads the connect rate as the first number to follow the
connect string on the same line as the connect string). Some modems,
however, (notably newer v.32bis modems) can be configured to return
very detailed information like this:
CARRIER 14400
PROTOCOL: LAP-M
CONNECT 57600/V32BIS/V42BIS
Now, if your connect string was "CONNECT", the value is not the 14400
you wanted, but the 57600 you didn't want. In this case, you need to
find the command in the modem manual that disables extended result
Telix v3.22 Questions and Answers 77
codes (often the S95 or S44 registers) and reverts to the simple
CONNECT 14400/ARQ/V42BIS string as above -- then Telix will get the
connect string you wanted.
Another option above (but not for all such modems) is to change the
connect string to match the word right before the number. Above,
you'd change the connect string to CARRIER. This one won't always
work, and it is best to disable extended result codes if you want
correct estimates.
Some modems do not return a correct response string at all, such as
the older US Robotics HST Dual Standard 1441 (v.32/ 9600) modems.
They return 9600 even if the connect was at 14400, and your estimates
in such cases will err by the difference.
Telix v3.22 Product Support 79
12. PRODUCT SUPPORT
Telix is a relatively large and complicated program. In order to sup-
port Telix and to provide a means of distribution, a BBS (Bulletin
Board System) for Telix support has been set up.
The Telix Software Support BBS is available 24 hours a day at 919-481-
9399. The Support BBS accepts calls from 300 baud to 9600 baud and be-
yond, including v.32/v.32bis calls, and HST calls at 14,400 baud. If
you have a Telix question or problem, or have found a bug in Telix,
give the support BBS a call. The latest version of Telix may also be
found on the support BBS.
If you're calling about a problem, try to be as specific as possible
when describing the problem. Include any relevant details, such as
your machine's configuration, Telix version number, resident software
installed, steps taken before the problem happens, and any other
things you feel are important. It is very hard to answer vague ques-
tions such as, "Telix doesn't work on my PC. Do you know why?".
At the current time, the support BBS is open to all callers. Since it
is extremely busy, it is almost certain that in the future it will be
restricted to registered users of Telix. Registered users will also
receive mailed notices of major updates to the program.
Telix v3.22 External Protocols 81
13. EXTERNAL PROTOCOLS
While Telix supports a very large number of protocols internally, it
also allows users to define up to 5 external protocol implementations,
for the utmost in flexibility.
External protocols are defined in the 'Protocol options' page of the
Configuration Menu. Basically, based on this configuration, when the
user selects a transfer with this protocol, Telix will either run a
specified DOS Batch file, or a TELIX SALT script file.
13.1 Batch File Method
──────────────────────────────────────────────────────────────────────
If a Batch file has been configured to be executed when the external
protocol is selected, TELIX will execute it and pass to it 3 parame-
ters (with the third sometimes being blank). The first parameter is
the baud rate. This is accessed within the DOS batch file as %1. The
second parameter is the comm port number. This is accessed as %2. The
third parameter is the reply the user gave when asked what file(s) to
transfer. If this is a download and this protocol has been defined to
not need a download name, this parameter will be blank. If this is an
upload via an external protocol defined as an "@" protocol (see
Configuration, Protocols), this parameter will be "FILELIST",
otherwise, will be the list of files to send. This parameter is
referred to as %3 in the Batch file.
It is now the responsibility of the Batch file to call a driver pro-
gram for the protocol, using the supplied info. For example, assuming
Telix didn't have built-in Zmodem support, a batch file called SZB.BAT
could be defined to perform Zmodem uploads using the commonly avail-
able DSZ program with the following command in it.
DSZ port %2 speed %1 sz %3
This would tell DSZ what files to transfer, and also would specify the
proper baud rate and comm port.
If DSZ were an "@" protocol, the command would be:
DSZ port %2 speed %1 sz @%3
13.2 Script File Method
──────────────────────────────────────────────────────────────────────
Alternately Telix can run a SALT script file when the user selects an
external protocol. The script should be compiled ahead of time (as ex-
plained elsewhere in this manual). The user's reply to the question of
what files to transfer is stored in the system variable _ext_filespec.
Telix v3.22 External Protocols 82
The script file is free to implement the protocol in whatever way it
wants to, such as calling an external driver program using the 'RUN'
function, or by actually performing the transfer itself.
Telix v3.22 File Formats 83
14. FILE FORMATS
For programmers who wish to write dialing directory handling utili-
ties, a text file describing the dialing directory format used by
Telix is available on the Telix Software Support BBS as T3FONFIL.DOC.
