18. SPECIAL KEYS
Ctrl-Break clears any typeahead, unlocks the keyboard, and stops
whatever function[1] ZCOMM is doing in a reasonably orderly manner.[2]
Ctrl-Break cancels kbdlock. It is not so abrupt as the NUKE key. The
B test condition tests whether Ctrl-Break has been struck since the
last purgek command.
Keyboarding ALT-N will NUKE (abort) the current command and return to
ZCOMM's command prompt.[3] If one or more scripts are active, the
current line number (counting from the first line in the script file)
for each level of script is displayed.* NUKE will terminate any
script. NUKE closes any transmit file, but not a receive capture
file. (A receive capture file may be closed with the "close"
command.) NUKE does not disconnect the modem by dropping DTR.[4]
Keyboarding ALT-Z appends the contents of the display screen to a DOS
file. The pathname is contained in the string parameter picture which
may be changed with the set command. The exact contents of the screen
memory are written to the file, with each screen character followed by
its attribute. A separate program, unpic is used to convert the
screen dump to a normal file that may be printed or displayed.
18.1 Special Keys during Protocol Transfers
Certain keys perform special functions when keyboarded during protocol
file transfers (XMODEM, Kermit, etc.).
F1 Keyboarding F1 causes a protocol timeout and forces a retry.
ALT-A Displays Kermit file transfer status.
ALT-B Cancels the current Kermit or ZMODEM batch transfer.
__________
1. Not necessarily the calling function or script
2. In the term function, Ctrl-Break sends a break to the remote
unless it has been redefined with a set command.
3. Use of this term, popularized in the J.F.K. administration, does
not imply endorsement of preemptive nuclear attacks on innocent
populations.
4. When in host operation waiting for a call, NUKE drops DTR.
(C) 1990 Omen Tech Inc Chapter 18 Special Keys
Version 17.78 TurboDial 2.35 Universal Line Printer Edition
ZCOMM User Manual 93
ALT-C Cancels the ZMODEM or Kermit session.
ALT-F Skips the current ZMODEM or Kermit file transfer.
ALT-Q Keyboarding Alt-Q during a protocol file transfer toggles a flag
that causes ZCOMM to disconnect when the transfer is completed.
This is most useful when downloading a long file. As soon as the
file is transferred, ZCOMM will execute the string parameter
quitcmd (if set) and then disconnect the modem. If keyboarded
during a Host Operation file transfer, ZCOMM will exit Host
Operation at the conclusion of the transfer. The state of the
quit flag is displayed each time ALT-Q is keyboarded.
ALT-S Keyboarding Alt-S displays status information on the console
screen only (even if in Host Operation). The pattern number of
the last successful search (-1 if no match), the active search
patterns (if any), and the line numbers of the active scripts (if
any) are displayed to aid script debugging.
ALT-V Keyboarding ALT-V will toggle the view option affecting the rb,
rc, rz, sb, sc, sx, and sz commands, and data transfers using the
Compuserve B protocol.
ASCII Keyboarding a normal ASCII character (in the range of 00 to 7F)
will send that character to the modem. This may be used for
protocol testing, or to terminate a modem's autodial handshake
without terminating ZCOMM's call retry count.
Ctrl-X All ZMODEM and many YMODEM and XMODEM protocol programs
recognize a dozen successive Ctrl-X characters as a session abort
command. If the remote computer appears to be "stuck" in a YMODEM
or ZMODEM transfer, keyboard ten Ctrl-X characters to abort the
protocol transfer.
During a protocol transfer, normal keys are sent to the modem when
Zcomm is waiting for or receiving a packet. This may be used to
reissue a file transfer command to the other computer if it becomes
apparent the original command was not accepted.
Other uses for this pass thru capability include protocol testing.
18.2 Local Editing Keys
Emacs style character editing reduces the number of keystrokes needed
to enter and edit commands and strings. Normally the cursor is at the
end of the line of text being keyboarded. Printing characters insert
themselves at the cursor location. The <ENTER> key enters/transmits
the entire line of text.
(C) 1990 Omen Tech Inc Chapter 18 Local Editing Keys

Right, Ctrl-F moves the cursor to the right
Ctrl-Left cursor WORD left
Ctrl-Right cursor WORD right
Ctrl-A cursor to beginning of line
Ctrl-E cursor to end of line
Del, Ctrl-D delete character at cursor
Backspace delete character to left of cursor
Ctrl-W delete word to left of cursor
Ctrl-End, Ctrl-K delete to end of line
Ctrl-R refresh (redisplay) the line
Ctrl-X delete entire line
Down, Ctrl-N next history line
Up, Ctrl-P previous history line
Ctrl-U Argument Count (not available in term function)
An initial Ctrl-U sets an argument count of 4. Successive Ctrl-U
characters multiply the argument count by 4. A decimal number may be
entered after Ctrl-U, and this number becomes the argument count.
EXAMPLE: ^U^U Left moves the cursor 16 left
EXAMPLE: ^U5X inserts 5 "X" characters
EXAMPLE: ^U5^U? inserts 20 "?" characters.
Unix/Xenix flavors do not support Emacs style editing in the term
function.

ZCOMM User Manual 95
19. MAIN COMMANDS
All commands and arguments must be entered in lower case except where
stated.
You may shorten some commands by typing just the first portion that is
shown in caps. For example, the "break" command may be entered as
"br". Whether or not you abbreviate the command, it must be entered
in lower case.
User defined Soft Keys are executed from the command prompt iff they
do not conflict with the permanent definitions described below.
Except where stated, multiple commands can be written on one line
separated by ; (semicolon). Commands that take a constant number of
arguments do not need a semicolon to delimit the end of the command.
If in doubt, use a semicolon to separate multiple commands.[1]
@ The at sign may be used to indicate a telephone number starting with
the Touch-Tone(TM) A B C D * or # codes or a character escape. If
the phone number contains spaces, it must be enclosed in double
quotes. The leading @ is not sent to the modem.
EXAMPLE: @#*-123-4567 Dials #*-123-4567.
%l-234-567-8901 (%l:letter l) For normal long distance dialing, the
string parameter l (letter l) defaults to "1" (digit 1). To use an
alternative long distance service, set the l string parameter with a
modem command to dial the local access number, wait for the second
dial tone, and transmit the account number.
SEE ALSO: "setsavenet" telephone directory entry
A string of alternate phone numbers may be specified with the "+"
construction shown below.
234-5678 A number given as a command invokes the dial script to
attempt a connection with the specified number. Iff the modem is
currently connected to a remote modem, and the B numeric parameter
is non zero, ZCOMM pulses Data Terminal Ready, terminating the
connection. ZCOMM character escapes may be used within the number
string to represent special characters.
__________
1. A space or two after each semicolon makes scripts easier for
humans to read.

Version 17.78 TurboDial 2.35 Universal Line Printer Edition
ZCOMM User Manual 96
EXAMPLE: 234-5678
When carrier is detected, ZCOMM executes the mconnect string (if
set) and proceeds to the next command
One or several alternate phone numbers may be specified by appending
the previous number with +234-5678 for as many alternate numbers as
are desired.[2] When a connection is made, undialed alternates are
forgotten. Alternate phone numbers need not support the same
speeds. A redial count given to the call command repeats the
sequence of alternate numbers.
EXAMPLE: cis speed 2400 239-6124/mnp_s+239-6126/mnp_s+232-1032/300
This script line attempts a MNP (with software slow control) call to
the first two numbers, then a 300 bps call to the third number if
neither of the first two connected.
Iff no connection is made, script processing at the current level is
terminated.
A number of modifiers are available depending on the type of modem
and the choice of dialing script used. These are described in
Chapter 9.
SEE ALSO: nolog command, calllog string parameter, mcommand string
parameter
a: Change the default disk to a:. ZCOMM then prints the free storage
remaining on the selected disk. The specified disk must be included
in the string parameter disks.
abort Aborts any command or script in progress. Closes all script
files that may be open. Abort returns to the command prompt.
SEE ALSO: quit command
accept[[l]1] stringvar prompt (letter l, digit 1) Scripts often need
to prompt the user for file names and menu choices.
Accept displays Prompt[3] to the user. ZCOMM then reads keyboard

ZCOMM User Manual 97
input into the specified string variable. Backspace and Ctrl-U
perform editing functions. Characters are accepted from the user
until <ENTER> is typed. If the H numeric parameter is non zero, an
empty string is returned if <ENTER> is not typed within the time
limit set by that parameter. Acceptl translates the user's response
to lower case. Acceptl1 returns a 1 character string in lower case
after the single character is keyboarded.
Prompt is processed for string substitution and character escapes.
If the result begins with an ESC character, ZCOMM does not
reposition the cursor before accepting the string. In writing
scripts, it may be useful to save the current screen location with
an escape sequence, then restore it with an escape sequence encoded
in the prompt string.
EXAMPLE: accept s1 File: Displays the prompt File: and reads the
keyboarded response to string parameter s1.
EXAMPLE: acceptl1 s0 "Enter Menu Choice" Reads a single character
from the user, translates it to lower case, and assigns it to s0.
EXAMPLE: accept s0 "\E[20;60H\E[KFile Name: " Places the cursor at
line 20 column 60, clears the rest of the CRT line, displays the
prompt, and accepts input.
EXAMPLE: accept s6 " Your \E[1mFirst\E[0m name please " Uses
boldface video to highlight First as it appears in the prompt.
EXAMPLE: accept s2 "File "; rc %s2 Prompts the user for a file name,
then receives that file with XMODEM/CRC protocol.
EXAMPLE: accept xpassword "\E[mMaster Password: \E[8m"; lput "\E[m"
Uses invisible video (ESC [ 8 m) to allow a password to be entered
without visible echo. The ESC [ m sequences reset the display to
normal (visible).

ap file1 file2* (Append) Appends the contents of file1 to file2. If
file2 does not exist, it is created. Wildcards are not allowed.
The ap command closes any files that have been opened by the create,
f, open, t or > commands. File1 and file2 are processed for string
parameter substitution.

apd file1 file2* (Append-Delete) Appends the contents of file1 to
file2, then deletes file1. If file2 does not exist, it is created.
If an error is detected writing file2, file1 is not deleted.
Wildcards are not allowed. The apd command closes any files that
have been opened by the create, f, open, t or > commands. File1 and
file2 are processed for string parameter substitution.
EXAMPLE: apd %item Z%item.tmp
bdump outfile Dumps the contents of the modem interrupt input buffer
to outfile. This command is useful for debugging as outfile will
contain the last characters received from the remote regardless of
what ZCOMM commands have been executed. The most recently received
data appears at the end of outfile. This command "tells it as it
is", writing all 8 bits of each character to outfile. If few
characters have been received from the remote, some of outfile will
consist of nulls or garbage. The bdump command is often used as a
post mortem diagnostic dump after a failed script or file transfer.
This command is not available on OS/2, and X.PC flavors of ZCOMM.
bg Indicates ZCOMM is running in the background with no user at the
keyboard.
SEE ALSO: fg command, df test condition
BReak Sends a 200 millisecond break signal.
N.B.: Some modems do not correctly pass the break signal to the
remote.

BROwse pathspec Browse through the files specified in pathspec. If
pathspec is empty, all files are presented. For each matched
pathname, the filename, date, and length of the file are displayed.
The status line displays some of the commands which may be applied
to each file. Chapter 19.4 describes the browse subcommands, which
provide extensive capabilities for individually selected files.
bye Terminate the connection in progress by sending a long space and
then dropping DTR (Data Terminal Ready).[4] After a pause, DTR is
reasserted to allow the modem to originate or answer another
call.[5]
__________
4. The modem must be configured to use Data Terminal Ready (DTR).

The 7, A, a, b, C, c, E, e, g, H, h, i, j, n, o, P, p, q, r, S, s,
t, u, v, w, X, x, Z, and z modes are reset. The d mode is set. The
e, f, g, k, m, p, q, t, w, Kermit 8, zmodem C, e, l, L, p, t, T, w,
and W parameters are reset to their default values. The search
patterns are erased. Permanent string parameters set with the set
_svar command are set to empty.
If path has been specified, it is searched for a line beginning with
name. Otherwise, ZCOMM searches the telephone directory. An
optional modifier (string with a leading comma), if specified, is
not used in the directory search.
If the search is successful, the entire directory entry name is
copied to the remote string parameter. The complete argument
entered on the command line is stored in the args string parameter
visible to the called script. If the script has a READ ONLY
attribute, ZCOMM is unrestricted during execution of the script.
ZCOMM then executes the commands on the rest of the line (if any),
and on succeeding lines beginning with a space or tab. If the v
numeric parameter is greater than zero, each command from the file
is displayed on the screen before it is executed.
It is not necessary to type the entire name as it appears in the
telephone directory, as ZCOMM will find the first entry that name is
a prefix of. Iff name is empty, execution begins with the first
line of path.
EXAMPLE: call cis1200
call cis1
call cis.C:/newscript
EXAMPLE: call genie,upl Invokes the genie telephone directory entry
with the modifier ,upl available to the called script.
The call command is not limited to making connections. For example,
"call host" in the distribution PHODIR.t file conditions a Hayes
compatible modem to answer incoming calls silently, set parameters,
and activates ZCOMM's host operation.

ZCOMM User Manual 100
Most directory entries include a telephone number to dial. If ZCOMM
is used with an autodial modem, the number of retries N (default
none) may be specified.
EXAMPLE: call -40 cbbs-r Attempts 40 retries before giving up.
The interval between retries is set by the i numeric parameter.
EXAMPLE: pi4 Sets the interval between retries to 4 seconds.
Words To the Wise: Abuse of the retry feature by continually calling
busy numbers may incur the wrath of the Telephone Company.
Especially with Message Unit Accounting, Big Brother may be watching
your telecommunications habits. Some long distance services (MCI,
Sprint, AT&T, etc.) charge for unsuccessful calls, especially if the
phone is allowed to ring (or ring busy) for more than a few seconds.
Consult your telephone company about legal limits to the number and
frequency of retries.
Since some computer services will disconnect within a short time if
no login is attempted, you should start communicating as soon as the
modems are connected. ZCOMM sounds the bell after making the
connection if retries have been specified.
The source, gosub and call commands may be nested with up to six
command/phones file descriptors open at once.[6] A label may be the
target of a call command provided the trailing colon is included in
name.
cat pathspec For Unix users, a synonym to the type command (q.v.).
cd [dir] Change to directory dir. If Restricted, dir is checked for a
parent directory ("cd .."), and absolute paths ("cd /src") not
prefixed by the home string parameter. Giving cd without an
argument changes to the directory stored in the home string
parameter.[7] ZCOMM then stores the current directory in the pwd
string parameter and displays it unless the v numeric parameter is
less than 0.
EXAMPLE: cd /tmp
__________
6. Deep nesting may require a decrease in the circular buffer memory
allocation, see Chapter 16.
7. The home parameter is set to the current directory when ZCOMM is
invoked, but may be changed with the set command.

point to a valid directory in order to enforce the intended
directory path restriction.

cd D:dir When a disk drive is specified with the cd command, the
current directory on that drive is changed but ZCOMM remains logged
in on the current drive and directory. If Restricted, dir is
checked for a disk drive ("cd b:/foo") not contained in the disks
string parameter.
EXAMPLE: cd D:/tmp
cdd D:dir Change to (log in to) disk D and then to directory dir on
the specified disk. If dir is not specified, the root directory is
assumed. ** This is a shorthand equivalent to a D: command followed
by a chdir dir command.
SEE ALSO: cd command
chat Enter the term function to chat keyboard to keyboard. Characters
typed by either keyboard are echoed to both ends, and RETURNS echo
as RETURN/LINEFEED. In Host Operation, chat exits if the caller
types Ctrl-Z.
Chat will become hostile if the other end also echoes characters.
(Try it sometime on a timesharing system; it's fun.)
close Writes the contents of the circular buffer iff a receive file is
open, then closes the receive and transmit files. ZCOMM complains
if no files were open.

crc pathspec Print the CRC-32 and character count for the specified
files. The crc command verifies the identity of two (or more)
copies of a file. Iff the lengths and CRC-32's of two files are the
same, the files are almost certainly identical. Comparing files
with the crc command is faster than transmitting a second copy for
character by character comparisons.
EXAMPLE: "crc", "crc *.c"
HINT: To generate a file containing the CRC's of the files in the

create [-modes] outfile If a receive capture file is open as the
result of a create or t filename command, write the circular buffer

with modes. The create command is especially useful when you don't
want to enter the term function immediately.
EXAMPLE: create -ys /tmp/cbbs.tmp[8]
SEE ALSO: > command
createx outfile Similar to the create command, but does not open
outfile if a file with the same pathname already exists. The
resulting error message may be suppressed by setting the v numeric
parameter negative. Scripts may test for success with the r test
condition. The createx command may be used to manage semaphores to
lock resources or work entries used by multiple instances of a
program. The createx command is available on Unix and OS/2 flavors.

demand password Scripts must often verify a caller's identity by
asking for a password. The ZCOMM password command allows a caller
three chances to enter a given password. Failure results in
disconnection.
Password is processed for character escapes and string
substitutions. All security restrictions on string parameters are
enforced.
If the result is empty, no password is demanded. Otherwise the user
is prompted to enter a string matching password in the correct case.
Keyboard input is not echoed.
Three attempts to enter password are allowed. If the password is
not correctly entered, DTR is pulsed to force the modem to
disconnect the caller, and the ? numeric parameter is set negative.
EXAMPLE: demand %password Requires the caller to enter a string
matching the contents of the password string parameter.
dir pathspec Display pathnames matching pathspec alphabetized across
the page. Wildcard filename expansions are alphabetical.
EXAMPLE: dir
EXAMPLE: dir y*.c *.h
dirr pathspec Displays the directory with length and creation date of
each file. dirr displays the number of files matched, number of
blocks, number of kb in those files, and estimated transmission time
at the current transmission speed assuming the fastest protocol
available (ZMODEM or YMODEM-g). XMODEM and Kermit transfers take

ENAble {-modes} Enable mode(s) affecting the term function. Chapter
21 describes modes affecting the term function.
EXAMPLE: ena -h Enables half-duplex (local echo) Half-duplex mode
causes the term function to display keyboarded characters.
estimate length [speed] Use the specified length and optional
specified effective speed when displaying information for the next
receive file. A length of 0 bypasses the length substitution. Once
a speed (in effective bits per second) is given, it is used for all
locally displayed transmission time calculations until the next
speed or port command.
EXAMPLE: estimate z2 Uses the file length stored in string variable
z2 in calculating the transmission time estimate for the next
received file.
EXAMPLE: speed 19200; estimate 0 2400 Use an effective transmission
speed of 2400 for transmission time estimates instead of the 19200
bps interface speed.
exit [code] Exit to the operating system with optional code.

EXPand sourcefile pathspec ** For each pathname in pathspec, execute
the commands in sourcefile with the string parameter item set to the
current pathname. The commands in sourcefile must not themselves
contain wildcards (* or ?) or directory pathnames. If no files
match pathspec, sourcefile is not executed. If the script executed
has a READ ONLY attribute, ZCOMM is unrestricted during execution of
the script.
EXAMPLE: expand plxupl 001* Executes the script plxupl once for each
file matching the wild card specification 001*.
EXAMPLE: expand a *.arc where the file a contains:
obey "!pkxarc -v %item >> arclist"
lists the contents of all .arc files to arclist.
Chapter 99 explains the use of this command in more detail.
f [-modes] file The f (think of "file") command initiates transmission
of file with the term function. One or more term function modes

(described in Chapter 21) may be enabled with the optional modes
flag.
If q (TWX) mode is enabled, transmission pauses until the called
system's answerback restarts it with an XON, or until g mode is set.
Otherwise, any XOFF induced transmission pause is reset.
Once the file has been opened with the f command, a pattern match or
keyboarding F1 or ALT-X will exit the term function with file
incompletely transmitted. The rest of the file may be transmitted
by the t, F2, or wait commands.
EXAMPLE: f -px message Uploads message paced by the p mode, which
sends a carriage return and pauses at the end of each transmitted
line until the remote responds with the prompt character (default
line feed). The x mode makes the term function return to the script
after the file has been transmitted.
EXAMPLE: set eolstr "\r."; pp1000; pg58; f -p file Is useful for
uploading a prepared message to a CompuServe bulletin boards using
the "SIG" editor (not FILGE). The eolstr setting sends a carriage
return and period after each line to prevent the CompuServe software
from reformatting the message. Pp10000 Sets the pause timeout to a
long time. Pg58 Sets the prompt character to ":". f -p file
Transmits the file.

fail Terminate the current expand command, otherwise return from the
current script level with failure status.
If called directly by another level of script, that level is
terminated.
The fail command also causes the term function to exit, to allow a
function key to be programmed with a macro that exits the term
function.
If called implicitly by a number presented for dialing, fail
terminates the current dialing attempt. If no retries are left, the
call is abandoned.

fget outfile * Gets 8 bit raw data from the modem to outfile without
any protocol. No data is displayed on the screen. Keyboarding F1
terminates recording; any other keyboarded character is sent to the
remote. Iff the g numeric parameter is set to to some value other
than its default of 10 (line feed), the fget command terminates upon
reading and storing a character matching the g numeric parameter.
The fget command also terminates recording on loss of carrier detect
signal.
This command can be used when the flow of data from the remote
cannot be regulated. The maximum rate attainable without loss of
data is limited by the maximum interrupt latency of the operating
system and active device drivers. The time required to write a 512
character buffer to disk may also limit the maximum average data
rate. Each 512 character block must be written before the modem
interrupt input buffer overflows with new data. If the startup time
for a floppy disk is excessive, better results will be obtained
writing to a hard disk or ramdisk[9] if a suitable device is
available. Tests with an IBM Personal Computer, DOS 2.1, and a
Maynard Electronics hard disk suggest that no characters are lost at
9600 baud. (Your results will vary depending on your configuration
and programming habits. California estimates lower.)
EXAMPLE: fget rawdata
find string pathspec Find and display lines containing matches to
string in the specified files. Lower case characters in string
match either case; upper case characters in string match upper case
characters only. If string contains spaces, tabs, or semicolon, it
must be enclosed by double quote characters. ZCOMM C style escapes
may be used to represent control characters and string parameters to
be searched for. Assuming normal DOS files (with CR/LF at the end
of each line), a \n at the beginning of string forces a match to the
beginning of a line. A \r at the end of string (\n if the file(s)
have no returns in them) forces a match at the end of the line.
The file name being searched and its length are displayed in the
status line. For each line that contains a match to string, the
file name (if more than one file), line number, and the text of the
line are displayed.
EXAMPLE: find count *.c Finds all occurrences of count or COUNT in
the named files.

with the matched line. Otherwise, it is similar to the find
command. When the screen is filled up, the prompt More? appears.
Typing space displays another screenfull. Typing n skips to the

findq string pathspec Silently searches the specified files for the
first line matching string. The processing of string is identical
to the find command described above. Upon a successful search, the
contents of this line are stored in the z0 string variable and the ?

finish Terminates Kermit server operation on the remote system.
fput file * Puts data from file to the remote at maximum speed without
any protocol. After each 512 characters, the number of characters
transmitted is displayed in the status line, and the keyboard is
polled. Any key will abort the transfer. This is the fastest way
ZCOMM can transmit characters to the modem, with possible peak
speeds greater than 19kb. This command is useful for testing RS232
peripherals at high peak rates such as 56 kilobaud.
EXAMPLE: fput datafile
fpute file * Echoplex transmit a file to the remote, waiting for the
correct echo to each character transmitted (for Throttle/10
seconds). The echoed character is sent to the CRT screen. If fpute
receives a space as an echo to a tab, fpute waits for the spaces to
stop echoing for at least 100 milliseconds before resuming
transmission. Transfer speed thus suffers when tabs are present in
the transmitted file unless the remote can be set to echo tabs as
tab characters instead of expanding them to spaces. Throughput is
less than 1/3 of normal because of the echo delay.
Fpute counts each time the correct character is not echoed as an
error.
With n mode, fpute transmits only a linefeed at the end of each
line. With r mode, fpute transmits only a carriage return at the
end of each line. Most applications would use one of these modes.

Version 17.78 TurboDial 2.35 Universal Line Printer Edition
ZCOMM User Manual 111
CPMEOF (Ctrl-Z) terminates the file transmission unless b mode is
set.
Because fpute waits for the correct echo to each character sent,
fpute should be used for transmitting characters to programs that
echo exactly.
Often it is easy to write a simple receive routine to synchronize
with the sender by echoing each character received. On some
microcomputer systems, the device "TTY:" does just that. Fpute is
especially useful for "spoon feeding" files to the serial inputs of
microcomputers and minicomputers.

get filespec Instructs a remote Kermit server to the transmit the
specified file(s), then receives them. The form of filespec varies
with the remote system; it must be quoted if it contains any special

server; use kermit rb to receive files from a regular Kermit
program.
goback label Search the current script file for label: and execute
commands starting at that line. The goback command begins the
search at the beginning of the file. It is faster than the goto
command which begins the search at the current line.
SEE ALSO: goto command
gosub name[.scriptfile] Call a script as a subroutine. The phone
directory is searched for name unless another file is specified with
.scriptfile. Gosub has the same action as the call command (q.v.),
but does not reset modes, disconnect the modem, or modify the remote
parameter.
EXAMPLE: gosub dosig Executes the dosig entry in the telephone
directory.
EXAMPLE: gosub .%lib/baud.t Executes the commands in c:/yam/baud.t
assuming the lib string parameter contains c:/yam.
SEE ALSO: call command
goto label Search the current script file for label: and execute
commands starting at that line. A label begins at the first column
and ends with a colon (:). Iff label precedes the current script

grab svar Grab reads a line from the currently open transmit file into
the specified string parameter svar. Unless b mode is on, all
characters starting with the first CR and/or LF are discarded. Grab
inhibits transmission of the open file until g mode is explicitly
set by a command.
On end of file the transmit file is closed and the string parameter
is set empty. End of file can be tested with the t test condition.
SEE ALSO: putv command
HAndshake {off|sw|on|cts|dsr|dcd|both|slow} Some modems and printers
cannot accept continuous full speed data. These devices send
control characters (XOFF and XON) for flow control, or generate a
hardware flow control signal on the CTS, DSR, or DCD pin. The
Handshake command controls the modem port hardware handshake
(default sw).[10]
If hardware handshaking is selected, an ON to OFF transition on the
specified line pauses transmission, and an XON character will not
override the hardware restraint.
After a timeout set by the S numeric parameter (default 60 seconds),
or if characters are in the keyboard input buffer, a warning message
is displayed, the restraint is released, and characters are sent.
As a special case, handshake on obeys output flow control with the
CTS input signal, asserts input flow control with the RTS output
signal, and disables the transmission of XOFF characters when the
modem input buffer becomes nearly full.
Some computers do not support concurrent disk and serial I/O at high
speeds. The handshake slow command drops the RTS signal to the
modem during disk writes when receiving files with YMODEM-g or
ZMODEM. The handshake slow command does not correct overrun
problems caused by TSRs and multitasking executives.
The handshake both command allows either CTS or XOFF to pause
output, in addition to asserting input flow control with the RTS
output. This is useful when the local modem uses CTS/RTS hardware
__________
10. ZCOMM automatically disables its software (XON/XOFF) flow control
when using XMODEM, YMODEM and similar protocols that require all
256 byte codes. These protocols may not work if the modem is set
for software flow control.

flow control, but calls a network such as CompuServe, Telenet, or
Tymnet that uses software (XON/XOFF) flow control.
The handshake dcd command enables d mode (q.v.). Subsequently,
selecting a different type of handshaking will disable d mode. Use
of handshake dcd is not recommended.
The "handshake off" command disables all flow control except for
XOFF characters sent by the term function.
The handshake command (without argument) releases flow control
(allows data to flow if it had been stopped by handshaking).
Changing the communications port with the port or portx command
disables hardware handshaking.
Operation of the handshake command varies with the operating system
and hardware used.
SEE ALSO: S numeric parameter
EXAMPLE: handshake cts Turns on CTS handshaking.
help The help command uses the helpfile or xhelpfile string parameter
depending on whether ZCOMM is in host operation. Normally, the help
command displays a command summary, pausing every 24 lines.
If the string parameter begins with the character @, ZCOMM uses the
rest of the parameter as the initial command to access a pop-up help
program. The contents of the f string parameter are added to this
command, separated by a space. Thus, if helpfile contains "@yhp
/umanh.hlp", giving the help command from the main prompt executes
the DOS command "yhp /umanh.hlp main".
If the called program leaves a file yamhelp.tmp containing script
commands in the current directory, ZCOMM executes this file with a
source command and then deletes it.
SEE ALSO: f, helpfile, xhelpfile string parameters, source command
history [histfile] Opens histfile for use as a dual 64 entry history
file for commands entered both at the ZCOMM command prompt and
online with the term function. Histfile is a random access file
used as a pair of circular buffers to save commands for recall.
Only a file created by a previous history command may be used with
the history command. If the specified histfile does not exist, it
is created. Histfile stores commands with T or more characters
where T is the value of the T numeric parameter.
(C) 1990 Omen Tech Inc Chapter 19 Main Commands
Version 17.78 TurboDial 2.35 Universal Line Printer Edition
ZCOMM User Manual 114
If histfile is not specified with the history command, the current
history file is updated and closed.
The history command may be given with a different file name whenever
desired to access useful commands saved from previous sessions with
a particular host or application.
When history is enabled, the Up and Down function keys scroll
through previously entered commands. Ctrl-P and Ctrl-N may be used
in place of Up and Down respectively. An old command so selected
may be edited with editing keys described in Chapter 18 and executed
with the <ENTER> key.
In the term function, the history accessed with the Up and Down keys
is displayed and edited in the status line. [11] A Ctrl-X clears the
recalled text and restores normal status line and keyboard
operation.
EXAMPLE: history /tmp/favbbs.hist
SEE ALSO: r command, T numeric parameter
N.B.: Do not give the history command before you have entered any
secret passwords from the keyboard as these will be saved in the
history file. The history command without an argument closes the
history file and disables command recall. Alternatively, the T
numeric parameter may be set to a large value to inhibit storing of
passwords in histfile.
Normally, histfile should be an absolute pathname to insure that the
same file will be used regardless of the directory from which ZCOMM
is called from.
The history command is not available when Restricted.
N.B.: Do not attempt to delete an open file on DOS, especially the
history file.
host The host command conditions ZCOMM to accept incoming calls
unattended. Host operation is described in Chapter 28. The EXIT
key F1 terminates Host Operation.

parameters to their appropriate values. Use the "host" entry in the
distributed PHODIR.t file as a prototype for your application.

term function does not act upon key strokes. If N is greater than
1, key strokes have no effect on protocol transfers. The Ctrl-Break
key and the command prompt reset kbdlock to 0. If N is 257, the
Ctrl-Break key does not reset Kbdlock. Kbdlock does not affect the

learn lfile TurboLearn(TM) Script Writer records timing information
and term function keystrokes to lfile. The TurboLearn program
tlearn.exe then generates a script using this data. Normally,
learning is initiated after the connection has been established, but
before the first prompt is received from the remote. This is best
accomplished with the F4 key, which activates the tlearn telephone
directory entry.
Function keys, cursor keys, reassigned keys, and scripts[12] should
not be used while learning.
When accepting passwords and other sensitive information, systems
sometimes acknowledge each keyboard character with #, *, x, or X,
instead of the keyboarded character itself. When this happens, do
not type characters faster than the remote responds to them.
The resulting script should be examined for evidence of keyboarding
mistakes, line noise, and dependence on prompts that change each
time you access the system.
The comments below apply when the tlearn script is not used.

From the main command prompt, execute the TurboLearn program tlearn
with a DOS Gateway.
After recording, the tlearn program reads lfile and generates a
series of pattern and put script commands to let ZCOMM search for
the prompts and respond with the proper keystrokes. The resulting
script file newscript may be accessed with the source command.
Alternatively, the last command above may be replaced with
!tlearn -d newdirname lfile >>phones.t
to add the new script to the end of your telephone directory.
The -d dirname causes tlearn to prepend the given new directory
entry name newdirname and the telephone number to the resulting
script commands. The redirection characters >> add the script
commands to the end of your telephone directory.
You can also use the -d newdirname option to tlearn to prepare a new
directory entry in a separate file. Then you can edit this file and
add it somewhere within your telephone directory.
The tlearn program also accepts a -r option to suppress a "return"
command normally emitted at the end of the generated script. This
tlearn option allows one to append an "off" command to the generated
script.
link * Link two serial ports. The link command allows remote access
to a computer or other device connected to another port. For
example, if port 1 is connected to an autoanswer modem and port 2 is
connected to a local timesharing machine, the link command would
allow dial-up callers access to the timesharing machine. Chapter
19.5 describes the link command.
list pathspec The list command uses standard DOS character output
routines and any installed CRT device driver instead of ZCOMM's own
CRT driver. The printer can be enabled with ^P given to DOS (not
ZCOMM). List the specified file(s).
This command closes any open transmit file. ZCOMM detects SQueezed
files and prints them in ASCII.* List pauses/resumes printing with
^S. Keyboarding ^C cancels, and ^X skips to the next file (it might
take a few whacks of the keyboard to get ZCOMM to hear it.) The list
command defaults to a type command when ZCOMM is in host operation.

lput string Displays string on the console display. String is
processed for character escapes. Lput is useful for scripts sending
cursor control codes to the screen. Control characters and escape
sequences used with the lput command are always decoded with ZCOMM's
