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.
BReak Sends a 200 millisecond break signal.
NOTE: 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 17.4 describes the browse subcommands, which
provide extensive capabilities for individually selected files.
bye Terminate the connection in progress by sending a long space and
dropping DTR (Data Terminal Ready). After a pause, DTR is
reasserted to allow the modem to originate or answer another
call.[3]

call [-N] name[.path][,modifier] Prepare ZCOMM for a new task and
invoke an entry in the Phone Directory.
The 7, A, a, b, C, c, d, E, e, g, H, h, i, j, n, P, p, q, r, S, s,
t, u, v, w, X, x, Z, and z modes are reset. The e, f, g, k, m, p,
q, t, w, and Kermit 8 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. 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.
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.[4] 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 type.
cd [dir] Change to directory dir. If Restricted, dir is checked for
parent directory ("cd ..") and absolute paths ("cd /src") that are
not a prefix of the string parameter Home. Giving cd without an
argument changes to the directory stored in the home string
parameter.[5] 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
SEE ALSO: pwd command, pwd string parameter
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. Chat will become hostile if the other end also
echoes characters. (Try it sometime on a timesharing system; it's
fun.) In Host Operation, chat exits if the caller types Ctrl-Z.
chek pathspec Print the "chek" CRC-16 and character count for the
specified files. The CRC-16 used is the 16 bit Cyclical Redundancy
Check used by the public domain CHEK.COM program. The chek command
verifies the identity of two (or more) copies of a file. Iff the
lengths and CRC-16's of two files are the same, the files are almost
certainly identical. Comparing files with the chek command is
faster than transmitting a second copy for character by character
comparisons.
EXAMPLE: "chek", "chek *.c"
HINT: To generate a file containing the CRC's of the files in the
current directory:
>chek.lst

4. Deep nesting may require a decrease in the circular buffer memory
allocation, see Chapter 15.
5. The home parameter is set to the current directory when ZCOMM is
invoked, but may be changed with the set command.

After the files are copied, run the commands above (with a different
file name), then compare the two files with DIF.EXE to detect any
that have changed.
SEE ALSO: crc, sum, wc commands
Source for a public domain Unix version of CHEK is available.
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.
closerx Iff a receive file is open, writes the circular buffer then
closes the receive file.
closetx Closes the transmit file, if it is open.
cls Resets display modes and clears the screen.
CONFerence Enters the term function with a 1 line window for composing
commands and text. Chapter 20.5 gives details.
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"
SEE ALSO: chek, sum, wc commands
Source for a public domain Unix/DOS version of CRC is available.
The crc command is available with flavors of ZCOMM with ZMODEM.
create [-modes] outfile If a receive capture file is open as the
result of a create or t filename command, write the circular buffer
and close it. Then create outfile for use with the term function
with modes. The create command is especially useful when you don't
want to enter the term function immediately.

del pathspec Delete the specified files. No message is printed if
files could not be deleted. No confirmation is requested for
massive deletes.
WARNING: As with all ZCOMM pathspec specifications, a directory name
expands to all files in that directory.
SEE ALSO: browse command
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. If the result is
empty, no password is demanded. Otherwise the user is prompted to
enter a string matching passowrd 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, dir *.c, dir y*.c, dir *.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
longer than the displayed estimates. Wildcard filename expansions
are alphabetical.
dird pathspec Long Form directory, sorted by date.
______________________________________________________________________
5. The y mode overwrites any existing file with the same name. The s
mode strips most control characters from the resulting disk file.

dirt pathspec Long Form directory, reverse sorted by date.
dirl pathspec Long Form directory, sorted by file length.
dirs pathspec Long Form directory, reverse sorted by file length.
dirx pathspec Long Form directory, sorted by file extension.
DISable{-modes} Disable mode(s) affecting the term function. Chapter
19 describes modes affecting the term function.
EXAMPLE: dis -t disables throttle (t mode).
display [[no]dismode] ... Without an argument, prints the display
modes. Display modes preceded by NO are turned off. With one or
more arguments, turn on the specified display mode(s). If an
argument is preceded by no, the specified display mode is turned
off. The display modes are:
nlmode Received newlines (linefeed) display as return/linefeed.
bell=visual Instead of sounding on the speaker, bell characters
cause flashing notes to appear on the screen.
overstrike Overstruck characters are displayed in bold face or
underline (reverse video on CGA) as appropriate.
lsi-adm3a Emulate Lear Siegler ADM3a and Televideo 9xx control
codes.
autowrap The 81st character prints on a new line with possible
scrollup.
stat=off Disables ZCOMM's status line.
warpdrive Provides higher display speed without scrolling flicker,
but causes noise (snow/chromablizzard) with CGA display
adapters.
vt100 Emulate DEC VT-100 and VT-102 display codes and most Teletype
5425 codes. VT-52 and Zenith H-19 codes are the default.
mapkb Allow escape codes from the remote or a file to active
alternate keyboard mapping.
3101 Executes IBM 3101 and TI 940 escape codes.
dumb Only null, bs, tab, cr and lf are executed, all others
display. As in real life, dumb takes precedence over vt100,
vt52, and lsi-adm3a emulation.

inhibit Inhibits the display (nothing prints).
SEE ALSO: Q mode
A display command argument changing the terminal emulation (vt100,
lsi-adm3a, 3101, dumb) disables nlmode and overstrike.
display nlmode nobell=visual turns on nlmode display mode and
turns off the visual bell.
display vt100 enables VT100/VT102 emulation used by many computer
systems.
dump pathspec Dump the named files in a side by side hex/ASCII format,
similar to the CP/M users' group DUMP program. The ending character
number is also displayed. Zero length files are not displayed.
echo[c|f] string Echo a line containing a single argument string in
reverse video. Tabs should not be used with the echo command. The
echoc command also echoes its argument to the capture file (if
open), without reverse video. The echof command echoes its argument
to the capture file only.
EXAMPLE: echoc "File not Accepted" outputs a line to the screen
and to the capture file.
EXAMPLE: echo "Dave, This conversation can serve no further
purpose." displays a line on the screen only.
SEE ALSO: lput command, r numeric parameter, character escapes
egrep[m] regular-expression pathspec ** Display lines in the specified
files matching regular-expression. Regular Expressions are
discussed in Chapter .
The egrepm command finds a line matching regular-expression in each
of the specified files, and then pages through the file beginning
with the matched line. At the end of each screen, ZCOMM accepts the
same subcommands used with the findm command.
EXAMPLE: egrep "^Subject:" *.* displays all lines that begin with
"Subject:".
SEE ALSO: findmore command
The egrep implementation does not strip the trailing CR/LF from
lines read from the disk. This affects use of the $ regular
expression magic character. When using the $ magic character, the
CR/LF at the end of normal lines must be represented as "..$".

This command is not available on small model flavors of ZCOMM.
else Execute the command(s) on the rest of the line if the last if
test performed on the current script level was false.
NOTE: While else statements in programming languages are connected
to a particular if statement according to syntax, the connection in
ZCOMM is to the last if statement executed on the level, regardless
of goto's.
ENAble {-modes} Enable mode(s) affecting the term function. Chapter
19 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.
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.
EXAMPLE: expand plxupl 001* executes the script plxupl once for
each file matching the wild card specification 001*.
Chapter 99 explains the use of this command in more detail.
f [-modes] file Initiates transmission of file with the term function.
One or more term function modes (described in Chapter 19) 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, X mode 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 inserts a 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.
SEE ALSO: b, g, p, r, n, t, w, x, X modes, eolstr string parameter,
t and wait commands
fail Return from the current script level with failure status.
If called directly by another level of script, that level is
terminated.
If called implicitly by a number presented for dialing, fail
terminates the current dialing attempt. If no retries are left, the
call is abandoned.
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.
SEE ALSO: egrep command
FINDMore string pathspec Findmore finds a line matching string in each
of the specified files, and then pages through the file beginning
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
next instance of string that has not yet been displayed. Typing ^Q
or ^S displays one more character from the file. Typing ^X skips to
the next file.

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
characters or spaces. The get command only operates with a Kermit
server; use kermit rb to receive files from a regular Kermit
program.
gosub name[.path] Call a script as a subroutine. The phone directory
is searched for name unless another file is specified with .path.
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 is a line with the label
starting in the first column followed by a colon. Iff label
precedes the current script line, the goback command will locate the
target label more quickly.
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 {on|cts|dsr|dcd|both|off} 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 off).
If hardware handshaking is selected, an ON to OFF transition on the
specified line stops 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
(C) 1987 Omen Tech Inc Chapter 17 Main Commands
Revised 09-05-87 Universal Line Printer Edition
ZCOMM User Manual 71
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.
The command handshake both allows either CTS or XOFF to stop output,
in addition to asserting input flow control with the RTS output.
The handshake dcd command enables d mode (q.v.). Subsequently,
selecting a different type of handshaking will disable d mode.
The handshake command releases flow control (allows data to flow if
it had been stopped by handshaking).
Changing the communcations port with the port or portx command
disables hardware handshaking.
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 used the
rest of the parameter as the inital 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 containg 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
host The host command conditions ZCOMM to accept incoming calls
unattended. Host operation is described in Chapter 99. The EXIT
key F1 disengages operation state.
NOTE: The host command is normally given only by a script that sets
parameters to their appropriate values. Use the "host" entry in the
distributed PHODIR.T file as a prototype for your application.

Kermit rb [-options] Kermit rb receives files using the Kermit file
transfer protocol. Chapter 18 describes the available options.
File names are given by the sending program. The Kermit programs
must have compatible parity settings as described in Chapter 12,
Kermit Protocol.
Kermit rb receives files from a regular Kermit program; use the get
command to receive files from a Kermit server.
EXAMPLE: kermit pi1; kermit r.R downloads files from an IBM
mainframe.
When the remote Kermit starts sending, If K (Kermit autodownload)
mode is enabled (the default), the ZCOMM term function will sense
the remote Kermit's parity setting and download files without user
intervention.
Kermit sb [-options] pathspec Kermit sb sends the specified files to
either a regular Kermit program or a Kermit server. Chapter 18
describes the available options. The Kermit programs must have
compatible parity settings as described in Chapter 12, Kermit
Protocol.
EXAMPLE: kermit sb file ... sends the specified files to an IBM
mainframe.

EXAMPLE: The script fragment
pat 1c "///BEGIN///" "@ki create -+ print.fil"
pat 2c "///END///" "@close"
wait -f30000
will capture the data that arrives between "///BEGIN///" and the end
of the string "///END///". Other data from the remote will not be
captured to disk. The long pattern match fail time (30000 seconds)
makes the the cycle repeat almost indefinitely.
SEE ALSO: W mode
kill Erases all data stored in the circular buffer and restores the
buffer pointers to their initial positions.
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 TruboLearn 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[6] 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.

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.

Login to the bulletin board as usual. If you make keyboarding
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 shell escape.
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.
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. List stops/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.
SEE ALSO: l numeric parameter, l test condition
menu Execute script commands from the file name stored in the string
parameter menu.
message The message command allows a caller to keyboard a message
which will be appended to a file specified by the string parameter
messages. The message command allows the caller to type in 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.
more pathspec See page command.
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

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.
Parity, NULL, RUBOUT, XON, and XOFF characters received from the
remote do not affect pattern searches. If Kermit AutoDownload (A
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 24 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[8] 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.
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. 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.

port n Change the modem port to COMn. Legal values for n are 1...8.
Selecting a new port disables hardware handshaking. The currently
defined ports are:
COM1 3F8 IRQ4 (Standard IBM)
COM2 2F8 IRQ3 (Standard IBM)
COM3 3E8 IRQ4 (Alternate)
COM4 2E8 IRQ3 (Alternate)
COM5 2B8 IRQ3 (Columbia)
COM6 2B8 IRQ2 (Alternate for IBM)
COM7 2F8 IRQ2 (Alternate for IBM)
COM8 278 IRQ2 (Alternate for IBM)
COM9 Uses parameters set by the portx command.
COM1 and COM2 are the standard serial ports defined by IBM. COM3
and COM4 are supported by certain serial cards and modem boards.
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. 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. Certain disk controllers and mice
interfaces use IRQ2 and IRQ5. Do not use IRQ2 on a PC-AT (the extra
8259 is not reset). Do not select COM3 to COM8 unless you are
familiar with the I/O addresses and interrupt vectors used in your
machine. Ports sharing the same IRQ number cannot be used
concurrently.
The port command resets the d mode (which suppress the Carrier Lost
message).
EXAMPLE: port 2
ZCOMM begins with COM1 unless overidden by the DOS DPORT environment
variable.
EXAMPLE: C>set DPORT=2

private The private command allows a caller to keyboard a message
which will be appended to a file specified by the string parameter
private. The private command allows the caller to type in 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.
put string The put command transmits string to the remote. Use the
put command for transmittting 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 22. 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.
NOTE: 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

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.
CRC-16 is not the default because most IBM bulletin boards and
commercial modem programs only support the 8 bit checksum. Chapter

specified is odd, or equal to 110, two stop bits are transmitted;
otherwise one stop bit is transmitted.
EXAMPLE: speed 1200
NOTE: Some 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
