kill Erases (flushes) all data stored in the circular buffer and
restores the buffer pointers to their initial positions.
kill [-signum] procnum Available on Unix and OS/2 flavors, this form
of the kill command supports interprocess communications. If signum
is absent, the kill command checks for the existence of the
specified process, but does not send it a signal. Success sets the
? numeric parameter to 0, otherwise -1.
SEE ALSO: createx command, Unix kill(1)
l, ll, ls, lx For Unix users, synonyms for the dir commands.
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.
EXAMPLE: kill
123-4567; learn lfile
From the ZCOMM main command prompt, enter the desired phone number.
When ZCOMM connects, the learn command enters the term function with
learning (recording) turned on.

mistakes, you can edit the script file later.
ALT-C F1
Terminate learning with ALT-C, and return to the main command prompt
with the F1 key.
!tlearn lfile >newscript
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.
EXAMPLE: list *.cq
SEE ALSO: browse, type, page commands
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
default extended VT52/Z19 emulation, which also recognizes ANSI "ESC
[" sequences, regardless of which display emulation is selected.
Unlike the echo command, lput does not display in reverse video and
does not add a carriage return/linefeed to its argument.
SEE ALSO: echo command
lputp string Outputs string to the line printer. String is processed
for character escapes. Strings with embedded nulls (represented
with the \000 character escape) may be used. The lput command
should not be used if the printer is jammed, out of paper, or off
line. These conditions may be tested with the l test condition.
This command is not allowed when ZCOMM is Restricted.
EXAMPLE: if l lputp "\E\017" If the printer is ready, ZCOMM sends
ESC SI to select compressed printing on an IBM 80 CPS printer.

mput string The mput command transmits string to the remote at full
speed. String is processed for character escapes. Unlike the put
and putw commands, mput does not display characters coming from the
remote (they are held in the interrupt buffer). Control and other
special characters may be entered with character escapes. If a
carriage return should be sent, it must be explicitly coded with \r
at the end of the string.
SEE ALSO: put, putw commands
nolog * Suppress generation of the next log entry (of any kind).
EXAMPLE: mysys nolog speed 1200 123-4567 t
Suppresses the log entry that would otherwise be made if the calllog
string parameter is set.
nulls n When accessing ZCOMM in host operation, nulls sets the number
of nulls (default 0) sent after each linefeed to allow slow
terminals time to scroll.
EXAMPLE: nulls 4
o Terminates a data call by dropping DTR (Data Terminal Ready). DOS
ZCOMM drops Clear To Send (CTS) as well as DTR if hardware flow
control was selected with the handshake command. A bye or speed n
command must be given to reassert DTR before making or answering
another data call.[13] The o command does not release ownership of
the serial port.
SEE ALSO: speed, bye, off, port commands
obey string Sometimes one wishes to execute the contents of a string
parameter as a ZCOMM command. Other times one needs to reference a
pathname stored in a string parameter in the context of a command
that does not itself perform string substitution on its argument(s).
Obey executes string as a ZCOMM command. Character escapes in
string are substituted before execution.
EXAMPLE: obey ">>%s0" Redirects the output of utility commands to
the pathname stored in string parameter s0.

EXAMPLE: pat 19c "OBEY-LAST" "@obey %y2" Sets pattern 19 to execute
the previous line received from the remote when the string "OBEY-
LAST" is received.
N.B.: The remainder of the line after the obey command will be
executed unless execution of string is terminated by a return or
fail command. The construction obey "if xxx goto foo" May be used
only if no commands follow the obey command's string argument.
N.B.: Backslashes in file names used with the obey command must be
escaped.
N.B.: When the obey command is used to substitute file names, file
names containing separator or operator characters such as & may
change the syntax of the resulting command. For instance, the
pathological but legal DOS filename foo&&999.bar would cause obey if
f%thisfile gosub dofile to expand to if ffoo&&999.bar gosub dofile
to parse as a test for a match to an illegal pattern 999.
off Disable the modem by dropping DTR (Data Terminal Ready), [14]
release ownership of the serial port, and exit to the operating
system. DOS ZCOMM drops Clear To Send (CTS) as well as DTR if
hardware flow control was selected with the handshake command.
Exit status is the value of the ? numeric parameter.
The next program must select the port and initialize it to reassert
DTR before making or answering another data call.
SEE ALSO: bye, x, o, port commands
on [condition rest-of-line] * Executes rest-of-line if condition is
true. Condition is tested after each command line executes, unless
a return or fail command is executed, or when pattern is the last
command on the line. An on command without predicate (on a line by
itself) cancels the on command active at that script level.
EXAMPLE: on
The term function may be accessed with the wait command and no
patterns active to force an exit on loss of carrier detect or
pattern search timeout. Otherwise, ZCOMM could remain in term
function until a command is keyboarded. Typical commands to use
with the on statement are goto, return, off, and abort. Chapter 27
describes the testable conditions.
One active on statement is available for each level of script. The

on statement does not propagate to succeeding script levels.
When rest-of-line is executed, the on statement at that level is
canceled. An on command cancels any previous on command at that
script level.
EXAMPLE: on !c goto fooend Branches to fooend if the carrier drops
out.
SEE ALSO: wait, if commands
N.B.: No other commands may be on the line after the on command
except for its predicate.
open [-modes] file Opens file for transmission with the term function
with modes. The open command should be used when you don't want to
enter the term function immediately, or are already in it. In other
situations, it may be necessary to open the file before dialing to
allow transmission immediately after connection, without the delay
of opening the file from a floppy disk.
SEE ALSO: seek, read, close commands
page pathspec Type the file(s) specified in pathspec a screenfull at a
time. When the screen is filled up, the More? prompt appears.
Typing space displays another screenfull. Typing ^X skips to the
next file. Typing ^K or ^C terminates the command. This command
closes any open transmit file. ZCOMM automatically detects SQueezed
files and prints them in ASCII.*
EXAMPLE: page *.doc
SEE ALSO: browse, type, list, findmore commands
PATtern [n[cilpv$] string [action]] (n = 0...24) The pattern command
allows ZCOMM to search for up to 25 different responses from a
remote computer, and take action based on which of those responses
(or none) was "seen". A pattern match can execute specified script
command(s) "on the fly" (c modifier) or return control to the
calling script with an indication of which pattern was matched.
The pattern command causes the next t, f, or wait command (term
function) to search for string in the data received from the
remote/modem. String must be entered exactly as it will be received
from the modem, in the same case and with the same embedded spaces
or tabs. Control characters must be represented with ZCOMM
character escapes. The metacharacter \256 matches any single
character. ZCOMM %string substitutions may be used to define search
patterns. If the % character is to be searched for, it must be
represented as \045.
(C) 1990 Omen Tech Inc Chapter 19 Main Commands
Version 17.84 TurboDial 2.36 Universal Line Printer Edition
ZCOMM User Manual 127
Parity, NULL, RUBOUT, XON, and XOFF characters received from the
remote do not affect pattern searches. If Kermit AutoDownload (K
mode) is set, strings with SOH (Ctrl-A) cannot be matched. If
ZMODEM AutoDownload (Z mode) is set, strings with CAN (Ctrl-Z)
cannot be matched. If B protocol (c mode) is set, strings with DLE
or ENQ cannot be matched.
Strings of up to 33 characters each may be specified for
simultaneous search by the term function. The search patterns are
"global" among all script levels; a pattern command in a subroutine
affects the patterns set by the calling script(s) and vice versa.
The term function returns when one of the patterns is matched or
when the term function times out with f seconds with no characters
from the remote, as determined by the f numeric parameter, or when
carrier detect is lost. The first wait, t or f command given after
the pattern command begins the search.
When one of the patterns is matched, that pattern is marked as found
and its corresponding action is executed (if present). ZCOMM will
remain in the term function until there is a pause in data
transmission from the remote[15] unless the i or c modifier is used.
The following modifiers may be used. The c, i, and l modifiers are
mutually exclusive.
c The pattern is marked as found and action executed (if
present). The term function then continues searching.
Matching this pattern does not cause a return from the term
function. The condition for this pattern will test true, but
the n test condition is not affected.
i (Immediate) The pattern is marked as found and action executed (if
present). The term function then returns immediately.
l (line end delay) The pattern is marked as found and action
executed (if present). The term function then returns after
the first LF character following the matched string.
p (permanent) A pattern with the p modifier is not reset by the
pattern command without arguments. Patterns with the p
modifier may be used to search for disconnect messages within
an entire script. Permanent patterns are reset by the call
command, each item in the outcall queue, and an explicit
pattern command referencing that particular pattern number.

ZCOMM User Manual 128
EXAMPLE: pattern 20 "\nCLR" "@off" Disconnects and exits ZCOMM
if the phrase CLR is seen immediately following an LF.
v (verbose) The v modifier displays a message when the pattern is
matched. This is often useful when debugging scripts when the
large amount of output generated by large v numeric parameter
values is not desired.
EXAMPLE: pat 5v "Finished Already."
$ Sometimes the only way to recognize a prompt (as distinct from
the same string embedded in other data) is to require the
prompt to be the last thing sent by the remote, before a
pause. The $ modifier allows string to be matched only if the
remote pauses for 1 to 2 seconds after transmitting the last
character in string.
The optional action is a string to be sent to the remote, or
executed as a command if it begins with "@". Action is executed the
instant the last character of the pattern is matched, even if the i
modifier is not used. Action must not use the goto, f, t, or wait
commands.
The pattern command without any arguments clears the patterns that
don't have the p modifier, and terminates pattern searching. The
other events that terminate pattern search are a match to a pattern
that does not have the c modifier, a pattern search timeout, the
call, abort, or quit commands, a major error, or the NUKE key.
EXAMPLE: pat 0c$ "" "\21"
Sends one XON character every time there is a pause in output from
the remote. This recovers from situations where the remote computer
stops because it receiveed a spurious XOFF character, or lost an XON
character.
In the pattern n string command, if string contains a repeating
sequence such as foo in foofoobar, the search may be unsuccessful if
part of the phrase is received immediately prior to the desired
string (foofoofoobar).
port n Change the modem port to COMn. On DOS, the legal values for n
are 1...18.
Selecting a new port normally selects software handshaking
("handshake sw"). The PCDOS flavor enables both hardware and
software handshaking ("handshake both") iff the port speed exceeds
2400 bps and the Clear To Send (CTS) signal is active at the time
the port command is given.

COM5 2B8 IRQ3 (Columbia)
COM6 2B8 IRQ2 (Alternate for IBM)
COM7 2E8 IRQ5 (Alternate "COM3")
COM8 3E8 IRQ5 (Alternate "COM4")
COM9 Uses the port address and interrupt vector previously set by
the portx command.
COM11-COM18 IBM PS/2 COM1-COM8 ports
COM1 and COM2 are the standard serial ports defined by the IBM
Technical Reference Manual.
COM3 and COM4 are supported by many serial cards and modem boards.
COM3 and COM1 share the same dedicated hardware interrupt line, and
these ports may not be used at the same time. Likewise, COM4 and
COM2 may not be used at the same time.
Columbia computers support COM5.
COM6 to COM8 are alternate configurations that may be accessed by
cross jumpering between printer port decoders and serial port
enables on some multifunction boards.
COM7 and COM8 support alternative definitions for "COM3" and "COM4"
respectively.
COM11 to COM18 correspond to "COM1" to "COM8" on IBM PS/2 computers.
Only one of COM12-COM18 may be used at a time unless using the
special OS/2 comm driver for that board.
Since ZCOMM uses the interrupt line on the selected port, no other
program or device driver may use the same port address and/or
interrupt vector concurrently. Certain disk controllers and mice
interfaces use IRQ2 and IRQ5. Do not use IRQ2 on a PC-AT (the extra
8259 is not reset). IRQ5 is sometimes used by network cards and
printer ports. Do not select COM3 to COM18 unless you are familiar
with the I/O addresses and interrupt vectors used in your machine.
Ports sharing the same interrupt vector (IRQ number) cannot be used
concurrently.
The port command sets the d mode (which suppress the No Carrier
Detect message).

EXAMPLE: port 2
DOS ZCOMM begins with COM1 unless overridden by the DPORT
environment variable.
EXAMPLE: C>set DPORT=2
On Unix, the argument of the port command is a character special
file in the /dev directory. Unix and Xenix flavors have no default
port. If the DPORT environment variable is set, that port will be
selected when ZCOMM initializes. Otherwise, a port is selected by
the startup and/or dialing script. Typical values are tty01
(386/ix) and tty2A (Xenix).
EXAMPLE: DPORT=tty1A; export DPORT
SEE ALSO: handshake command, dport string parameter
portx hbase,irq * To support specialized multiport serial interfaces,
the portx command selects a communications port with a specified
hexadecimal base address hbase and Interrupt Request Line irq (3 <=
irq <= 7). The portx does not check its argument for validity. The
consequences of an invalid selection are quite undefined. The
specified base address and IRQ number are assigned to COM9, where
they may be used by the port command and the x numeric parameter.
The status line and s command will indicate COM9. This command not
available on X.PC, Unix, Xenix, or OS/2.
EXAMPLE: portx 3f8,4 Selects a comm port with a base address of 3f8,
using IRQ4.
SEE ALSO: intolink string parameter
private The private command allows a caller to keyboard a message
which will be appended to a file specified by the private string
parameter. Typically, private points to a private file inaccessible
to callers. ZCOMM prepends a "From" line using the callers name as
stored in the remote string parameter. The private command prompts
the caller to keyboard a "to:" name and up to 64 lines of text. A
blank line terminates the message. This command is intended for
short messages; long messages should be uploaded with a file
transfer protocol. Keyboarding is controlled by the Z numeric
parameter, which sets the hot zone column after which a keyboarded
space character begins a new line.

purgek Purge any characters the user may have typed ahead.*
purgel Purge any unprocessed characters received from the modem Line
(remote).*
put string The put command transmits string to the remote. Use the
put command for transmitting commands to a modem or a remote
computer system. String is processed for character escapes.
Control and other special characters may be entered with character
escapes described in Chapter 26. If a carriage return should be
sent, it must be explicitly coded with \r at the end of the string.
EXAMPLE: put "myname\r" Sends myname followed by carriage return to
the modem.
A \336 (octal 336) character causes a pause in transmission
(duration controlled by the p numeric parameter). This pause allows
one string to contain multiple commands.
EXAMPLE: put "\336ATZ\r\336\336ATX1 M0 S0=1\r" Pauses, sends ATZ\r,
pauses (twice because some modems take longer to reset!), and then
sends ATX1 etc. to the modem.
Transmission with put is controlled by the 7, 8, h, p, w, and t
modes.
SEE ALSO: putw, mput, putv commands
putw string The putw command transmits string to the remote, and
pauses for a period of time (determined by the q numeric parameter)
before returning from the term function to allow characters to echo.
Other than that final pause, putw operates the same as the put
command.
N.B.: Putw should not be used when the next operation will be a
pattern or wait command. If the expected response starts before the
putw command finishes, the following wait command will never get to
"see" what it is waiting for. In general, the putw command should
only be used as a short-cut for sending a command when the response
is known in advance and can be safely ignored.
SEE ALSO: put, mput commands
putv svar The putv command transmits svar to the remote without any
translation of character escapes. Putv does not append a carriage
return or line feed to the transmitted string.

modification date transmitted with the file.
EXAMPLE: pk3 Sets the k numeric parameter to 3, which kills pending
output stored in the circular buffer when ETX (Ctrl-C) (decimal 3)
is keyboarded in the term function.

queue clear clears all queue entries.
queue add [string] adds string to the queue after processing for
string substitutions. The string is added to the first empty
queue slot available. If string is absent, it is taken from
the next script line. A typical string would be a command to

Script entries used with the circular dialing queue should end
with a t command, which will enter the term function. To stop
the queue at that point, use the ALT-N (NUKE) key. NUKE

queue list lists the non empty queue entries.
queue run begins execution of the queue entries. The ALT-N (NUKE)
key, a fatal errror or any keyboarded character present after
the execution of the command in the entry terminates the queue
run command.
The queue commands are independent of the Outcall Queue available in

rb [-options] Receives with options 1 or more files using YMODEM batch
protocol. The rb command also receives files sent with SEAlink
protocol. Chapter 20 describes the available options. The pathname
and length of each file are transmitted in batch mode. If a file is
received in error (retries exhausted, etc.), the batch transfer will
terminate. If Restricted, a file received in error will be unlinked
(erased).
EXAMPLE: rb -y Receive file(s) with YMODEM replacing old files, if
any.
EXAMPLE: rb -g Receive file(s) with YMODEM-g.
Many programs claiming to support YMODEM actually use XMODEM with
1024 byte blocks; use ZCOMM's sx -k, rx and rx -g XMODEM commands
with these mutants.
SEE ALSO: YMODEM protocol, Chapter 13.
rb [-options] [dir] [file ...] Receives with options 1 or more files
using YMODEM batch protocol. An optional disk and/or directory dir
may be specified. The optional supplied pathnames file ... are
used in place of pathnames normally provided by the sending program.
If the sending program attempts to send more files than the number
of names supplied to the rb command, the transfer is aborted.
rc [-options] file Receives with options a single file using the Ward
Christensen XMODEM protocol, 128 or 1024 byte blocks, and CRC-16
instead of an 8 bit checksum. ZCOMM signals the sending program
that CRC-16 is to be used. After four errors while attempting to
receive the first sector, ZCOMM will cancel the CRC-16 option and
reverts to checksum operation.
The probability of an undetected transmission error is much less if
CRC-16 is used in place of the default 8 bit arithmetic checksum.
Omen Technology Inc Recommends use of the 16 bit CRC to maintain
data integrity at professional levels. Chapter 20 describes the
available options to the rc command. If Restricted, a file received
in error will be deleted.
EXAMPLE: rc foo.com

EXAMPLE: send -a *.asm
set[s|c] [[_]sparam string] Set String parameter sparam to string. As
with all ZCOMM strings, the string must be enclosed by double quote
characters if it contains spaces, tabs, or semicolons. Character
escapes must be used to represent special characters, including
return and linefeed if needed.
An optional leading underscore (_) prepended to sparam causes the
string to be cleared by the next call command.
EXAMPLE: set mprefix ATDT sets the modem dialing prefix for tone (T)
EXAMPLE: set f8 \PXXXXX Assigns a five character automatically
generated password (\PXXXXX character escape described in Chapter )
to function key F8. Once programmed this way, the F8 key will
transmit five nonsense characters determined by the xpassword string
parameter and the remote system's name as stored in the remote
string parameter by the last call command.
EXAMPLE: set _f1 "logout\r" Assigns the string "logout<ENTER>" to F1

The parameters that may be set with this command are described in
Chapter 25. Case is significant in parameter names.
Set without any arguments will display all non empty string
parameters and their values. If the v (verbose) numeric parameter
is non zero, all string parameters are displayed. The echo and lput
commands may be used to display string parameters ("echo %svar").
The setc command performs string substitutions and character escape
expansions on string before storing. The sets command performs
string substitutions on string before storing.
N.B.: Chapter 26 discusses string concatenation.
EXAMPLE: sets s2 "%z1" Assigns the second token (%z1) generated by
the split command to string parameter s2.
If other commands are to follow on the same line, a semicolon must
be used to separate the commands.
EXAMPLE: set s1 "su"; goto sendit Would be illegal if the ";" were
left out.
A string parameter may be set to empty with set sparam "" (empty
string enclosed by double quote characters).
EXAMPLE: pv1; set Displays all string parameters, including all Soft

EXAMPLE: sets s8 "s9 EQUALS %s9" Substitutes the value of string
parameter s9 in the argument before assigning it to s8.

N.B.: When defining function keys to be called from within the term
function, do not use the t or f commands. Instead use the create or
open commands to prevent excessive term function recursion.
Assigning a string to a function key with the set command causes
that string to be sent to the remote when the key is used within the
term function. If the string begins with @, the remainder of the
string is executed as a ZCOMM command.
EXAMPLE: set f3 "@rb" Assigns the rb command to F3.

set[s|c] [_]sparam This form of the set command allows strings
containing double quote (") characters to be defined.
Given with string parameter sparam, but no string, set reads string
from the next line verbatim, with only the trailing CR/LF removed.
The line should not begin with a space or tab unless one is required
for string. This form may be used for entering strings containing
double quotes. If a script is active, the next line is read from
the current script file, otherwise the user is prompted for it.
N.B.: This form of the set command cannot be used as the predicate
of an if command. The argument should not appear as a label or
telephone directory entry.
EXAMPLE: set outahost
@o; pk3; sp 2400; set disks "abcd"; putw "\336ATM0H1\r" Programs
outahost to drop DTR ("o"), set 2400 baud, allow disks a,b,c, and d,
and send an ATM0H1 (go off hook) command to the modem to busy out
the telephone line.
setn sparam expression The setn command stores as a decimal number the
result of an arithmetic expression consisting of decimal numbers,
string variables, the length of string variables denoted with %, and
the operators +, -, *, and /. The expression is evaluated strictly
left to right with 32 bit precision.
EXAMPLE: setn vv 1+vv
set? sparam condition The set? command stores a decimal number
representing the result of a test condition.
EXAMPLE: set? s0 S Stores the value of the S test condition

sleep deci-seconds Sleep causes ZCOMM to pause for the specified
tenths of seconds. This command may be used in a script with one or

source sourcefile Accept script commands from sourcefile. The source
and call commands may be nested with up to six[16] scripts open at
once.
If the script has a READ ONLY attribute, ZCOMM is unrestricted
during execution of the script.*
Command lines in files accessed by the source command must begin
with a tab, space, or label. Goto commands within sourcefile search
for labels in the same sourcefile. Gosub commands within sourcefile
access subroutines in the telephone directory accessed by the phones
string parameter.
EXAMPLE: bud source /usr/bin/caf/bin/callbud
This telephone directory entry pat calls a separate script file
containing commands to call a secret system. Placing this
information in a separate file keeps it out of the main telephone
directory file, which might be used on a number of computers.

SPeed m Set the transmission speed ("baud rate") to m. If the speed
specified is odd, or equal to 110, two stop bits are transmitted;

otherwise one stop bit is transmitted.
EXAMPLE: speed 1200
N.B.: Some older U.S. Robotics modems cannot accept the sustained
full speed output ZCOMM is capable of. Using speed 2350 corrects
such a problem with the U.S. Robotics Courier 2400.
Some 1200 and 2400 bps modems work better (lower error rate) if the
speed is set to slightly less than the nominal 1200 or 2400. This
also applies to communications networks that cannot accept sustained
full speed data, and to serial ports whose raw bit rate clocks are
slightly fast.
EXAMPLE: speed 1181 Sets the speed to 1181 bits per second with two
stop bits.
N.B.: Most timesharing minicomputers can send data from their serial
ports faster than they can receive. A timesharing port that
supports interactive operation at 19200 bps may not tolerate file
uploads above 2400 bps.
N.B.: Operation at high speeds is affected by the operating system
version, device drivers, memory resident software, and the
computer's hardware design. Chapter 34 describes common problems
encountered in high speed operation. The new generation
NS16550AN/NS16550FAN serial interface chips with FIFO buffers should
be used instead of 8250's or 16450's for best results at high speed.
This is imperative if disk caches, special device drivers or TSR
programs increase interrupt latency.

split svar Split (parse) string parameter svar into tokens stored in
string parameters z0...z9 using one or more of the characters in
string parameter ifs ("Internal Field Separator") to separate the
tokens. **
EXAMPLE: If string parameter s1 contains "hello there folks" and ifs
contains a space and tab, split s1 Assigns "hello" to z0, "there" to
z1, and "folks" to z2.
EXAMPLE: Let s0 contain "#1234567-This is big-time Parsing", and ifs
contain "#1256- ". The command split s0 Assigns "34" to z0, "7" to
z1, "This" to z2, "is" to z3, "big" to z4, "time" to z5, and
"Parsing" to z6.

EXAMPLE: If s0 contains "#1234567-This is ZCOMM Parsing", The
command split s0 "-" "" Assigns "#1234567" to z0 and "This is ZCOMM
Parsing" to z1.
EXAMPLE: If s0 contains "503-621-3746", The command split s0 "-" "-"
Assigns "503" to z0, "621" to z1, and "3746" to z2.
SEE ALSO: ss command, scripts, Chapter 99
ss svar regular-expression String Split svar according to regular-
expression. ** Regular expressions are described in Chapter 26.
The entire matched string (if any) is stored in the z0 string

Matched groups are stored in the z1...z9 string parameters.
Parameters which do not receive a matched string or substring are
set empty.
EXAMPLE: If string parameter s0 contains
From: Captain Midnight To: HBO Inc.
then the command ss s0 "From: (.*) To: (.*)"
places "Captain Midnight" in z1 and "HBO Inc." in z2. In this case,
z0 will contain the entire contents of s0.

garbage characters appended to make the file length a multiple of
128.
EXAMPLE: sx foo.com
EXAMPLE: sx -k foo.com Sends foo.com using 1024 byte blocks
N.B.: The receiver must be commanded to receive the file with an rx

ZMODEM protocol, only the sz command need be given. Otherwise, the
receiver must be commanded to receive the files with an rz command
or menu choice.

Each skipped file is counted as an error as indicated by the e test
condition and e numeric parameter. If the q option is used, files
skipped as a result of selective file transfers are not counted as
errors.
The pathname, length, and modification time of each file are
transmitted. Files which cannot be opened are skipped. An empty
pathspec sends all files in the current directory. A directory name
expands to all regular files in that directory.
If ONAME=x is given after the options (if any) and before the file
name(s), x will be used exactly as given as the COMPLETE destination
pathname instead of each file's actual pathname. It is the sender's
responsibility to use lower case for x unless the filename is really
supposed to be all caps.
EXAMPLE: sz -y ONAME=B:/spiked/secret /soviet/sdi/newlaser.doc
Results in the destination file secret on drive B: in the /spiked
directory. (Destination directories must exist and be writable).
If instead PREFIX=p is given after the options (if any) and before
the file name(s), p will be added to the destination pathname(s) as
a prefix. It is the sender's responsibility to use lower case for p
unless the prefix is really supposed to be all caps.
EXAMPLE: sz -y PREFIX=C:/foobaz/ /biff/bam/aardvark.wak
Results in the destination file "C:/foobaz/aardvark.wak"
EXAMPLE: sz *.com Sends all files with a .com extension.
EXAMPLE: sz -r ??log Crash Recovery sends only the new data if the
receiver has incomplete versions of these files.
EXAMPLE: sz -fn src/*.c src/*.h maildir

new files in the maildir subdirectory.
EXAMPLE: zcommand "sz -fn /bin /wp"

t [-modes] [capturefile] Invokes the term function for conversational
access to the remote. Normally, ZCOMM will remain in the
termfunction until the user keyboards F1.
If capturefile is specified, any currently opten capture file is
closed and capturefile is opened. A file previously opened by "t
file" is not closed by a t command given without an argument.
EXAMPLE: t file1 Creates file1 to capture data sent by the remote in
interactive conversation.
SEE ALSO: create command
If a file upload begun by an f or open command were in progress, the
upload will resume with the t command subject to the g mode.
In host operation, "t file" begins data capture, and received
characters are not echoed. When the remote sends ETX, EOT, or
Ctrl-Z, file is closed and the term function exits.
EXAMPLE: t comments.txt<ENTER>

trs svar string1 string2 String1 and string2 are first processed for
character escapes. Then translate string variable svar from the
character set in string1 into the character set in string2. *
Characters in String1 with no corresponding character in String2 are
deleted. Characters in svar not appearing in String1 are not
modified. The "trs" command may not be used in the body of a
"while" command.
EXAMPLE: trs s0 "\\{}" "/" Changes backslashes to slashes, and
removes "{" and "}" characters.
TYPe pathspec Type the specified file(s). This command closes any
open transmit file. ZCOMM automatically detects SQueezed files and
prints them in ASCII.* Type pauses/resumes printing with ^S.
Keyboarding ^C or Ctrl-Break cancels, and ^X skips to the next file.
<Ctrl-Home> clears the screen without pausing, avoiding scrolling.

unrestrict Prompts for a password and unrestricts ZCOMM if the
password exactly matches the contents of the unrestrict string
parameter. If unrestrict is empty or the given password does not
match in three attempts, the call is immediately terminated.
Unrestrict is used in Host Operation by a caller who wishes
unrestricted access to ZCOMM's computer to view confidential files
or perform maintenance.
EXAMPLE: unrestrict Prompts for a password (to match the unrestrict
parameter), then allows three tries to enter it correctly.
SEE ALSO: Host operation
usq pathspec * Unsqueeze the specified files back to their original
form. If pathspec is empty, ZCOMM checks all files in the current
directory and unsqueezes those that are found to be SQueezed. If
pathspec contains the name of a directory, all files in that
directory are checked. Iff a file has not been SQueezed, ZCOMM will
complain and proceed to the next file. ZCOMM checks the first word
of the file(s) to determine whether that file is SQueezed. If the
SQueezed file has been encrypted, such as a Demand Upgrade(TM) copy
of ZCOMM, ZCOMM will fetch the key file relative to the current
directory for use in decrypting.
N.B.: The original pathname and the keyfile pathname (if present),
stored in the SQueezed file is interpreted relative to the current
directory.
EXAMPLE: cd /tmp; usq a: Unsqueezes all the SQueezed files on A:,
placing the output files relative to /tmp.
EXAMPLE: usq ZCOMM.EQE Unsqueezes an encrypted Demand Upgrade(TM)
copy of ZCOMM. The key file (such as yampc08.key) must be in the
current directory.
videobios N Sets the video BIOS mode to N. This command is useful for
accessing the high resolution super EGA display text modes, such as
100 columns by 75 lines corresponding to high resolution 800x600
displays. The $ and # numeric parameters must be separately set to
agree with the new BIOS video mode.
The action of the video ROM BIOS to specific values depends on the
particular EGA/VGA ROM BIOS used. To support boards using an
extended code in the bl register, calculate N = bl + (256 * al).
