This is xcomm 2.2, which I mentioned in alt.bbs a few days ago. It
was written originally to do Xmodem transfers by one Eric Coe about 3
years ago. larry gensch got a hold of it and more or less took it
over last year, and added numerous features to it, most importantly
CompuServe's B Protocol, including Quick B support. It now supports
numerous configuration parameters, supports a small scripting
language, is capable of automatic response to CServe-ish ENQ xfer
requests, creates and respects HDB UUCP-style LCK files. It can be
installed setuid-UUCP because the entry module now includes a
setuid(getuid()) call before anything more than outbound line
initialization takes place.
Suggestions, improvements, bug fixes -> to me and I'll relay them to
the author. Note that there is a file doc/script.future which
describes the author's intended improvements. The next version (2.3
or 2.4, not sure which) is anticipated around the first of the year.

XFormat of the .phonelist file:
X
X1. The .phonelist must exist with the file name ".phonelist" either in the

X environment variable. The name of the phonelist file can be changed
X using the SET PFILE command.
X
X2. The .phonelist file is ASCII text (lines of text separated by newlines).
X It can be created and maintained using emacs, vi, or even ed.
X
X3. The first field of data in each line (after any whitespace and up to the
X next occurance of whitespace) is assumed to be a phone number in a valid
X format for the modem being dialed.
X
X4. Any text may follow the phone number.
X
X5. Special strings within each line:
X
X BITS=x (x=7|8) - Set the terminal mode mask to 7/8 bits.
X BAUD=nnnn (n=300|1200|2400|4800|9600) - Set the baud rate to the
X specified value
X SCRIPT=file Immediately after sending the autodial string, execute the

X CASE SENSITIVE!)
X
X6. A sample entry is shown below:
X
X 687-0374 CompuServe BITS=7 BAUD=1200, SCRIPT=cis.cmd
X
X The above entry indicates that the number to be dialed is 687-0374; the
X bit mask is to be set to seven bits (ignore high bits), the baud rate is
X to be set to 1200 baud, and commands are to be taken from the file
X "compusrv.cmd" in either the current or home directory.
X
X A sample .phonelist file is included in the XCOMM source code

X XCOMM SCRIPT QUICK REFERENCE
X XCOMM Release 2.2
X
X
X
XIntroduction
X
X Script files can automate some tedious tasks such as logging into a
X system. A script file is an Ascii text file and may be entered or
X edited using any standard Unix text editor.
X
X The script file is read line by line. Empty lines (consisting of white
X space only) are ignored. Comments are lines whose first non-space
X character is a pound sign (#).
X
X The script processor reads each script line, ignoring leading white
X space, into "words". A word is defined as either:
X
X - A sequence of characters delimited by white space; or
X - A sequence of characters enclosed in single or double quotes.
X
X The first word of a script file is considered the "command word."
X If the last character of the command word is a colon (:), the line is
X considered to be a LABEL (the object of a GOTO statement). Otherwise,
X it is assumed to be a script command and is interpreted as such.
X Command words are case insensative.
X
X Some commands take one or more arguments. Each argument is parsed as a
X single word as defined above. If blanks are required in an argument,
X the argument MUST be quoted using single or double quotes.
X
X Enclosed in the XCOMM distribution is the file "compusrv.cmd". This is
X an example script file (No, that is not really my user ID or my
X password in that file!), and shows the use of most of the available
X script commands. The script commands are self explanatory for the most
X part.
X
X
XStartup Scripts
X
X When XCOMM is started up, it looks for the file ".xcomm" in the current
X or $HOME directory. If it is found, it is executed. This is useful for
X setting your "basic" parameters without having to recompile XCOMM. For
X example, your startup file may turn CIS <ENQ> mode off, set your baud
X rate to 9600, and set 7BIT translation.
X
X
XScript Command List
X
X Below is the description of all commands that may be used in the XCOMM
X script language:
X
X
XCAPTURE ON|OFF
X
X The command CAPTURE ON will open the capture command; all characters
X received during WAITFOR processing will be appended to the capture file.
X The command CAPTURE OFF will close the capture file.
X
X This setting does NOT currently extend to terminal mode. This may be
X offered in a later release (probably through the SET command).
X
X
XDIAL <number>
X
X Dial the specified number. XCOMM supports generic "Hayes" compatible
X modems for dialing. Note that this command requires an actual phone
X number; the phonebook is not used for this function.
X
X
XECHO ON|OFF
X
X If the argument to the ECHO command is ON, all subsequent command lines
X that are processed will be displayed on the local screen. The exception
X to this is lines containing a TRANSMIT command. These lines will just
X print "TRANSMIT ...", so that passwords, etc. can be protected.
X
X If the argument to the ECHO command is OFF, scripts will execute
X quietly (this is the default setting).
X
X
XEXIT
X
X Terminate the script file prior to the end of file. Returns to terminal
X mode.
X
X
XGOTO <label>
X
X Go to the specified label in the script file and continue execution from
X that point. The label may either precede or follow the actual GOTO
X statement.
X
X
XIF <condition>
X <statements>
X[ ELSE
X statements ]
XENDIf
X
X Conditionally execute statements based on specified condition. XCOMM
X supports the following conditions:
X
X WAITFOR TRUE if the last WAITFOR command was successful
X LINKED TRUE if this script was executed from the phonebook
X
X Conditions may be negated using the prefix NOT or the character "!":
X
X !WAITFOR TRUE If the last WAITFOR command timed out
X NOT WAITFOR Same as !WAITFOR above
X
X The ELSE and ENDIF keywords must appear on their own lines. IF
X statements may not be nested.
X
X
XPAUSE <time>
X
X Suspend execution of the script for the specified number of seconds.
X This is usually used for timing considerations; for example, waiting a
X couple of seconds after receiving the CONNECT message and typing ^C to
X CompuServe.
X
X
XQUIT
X
X Terminate the script AND the XCOMM program (return to the shell).
X
X
XREDIAL
X
X Redial the last number dialed using the DIAL command OR the phonebook.
X
X
XSET <parameter> <value>
X
X Sets the specified parameter to the specified value. The SET parser
X used in command mode is used, and the parameters/values are identical.
X Refer to the main documentation for information on the SET command.
X
X During script processing, internal status messages are NOT displayed on
X the local terminal (eg, SET 7BIT ON in a script file does not display
X the new value on the terminal). This may be changed in the future
X (probably tied to the ECHO setting).
X
X During script processing, specifying SET alone is an ERROR... there is
X no way currently display the current status of the SET-able parameters
X during script processing.
X
X
XTRANSMIT <text>
X
X Transmit the specified text to the remote. The text argument should be
X quoted (using single or double quotes) if there are spaces to be
X transmitted. The text is transmitted AS IS (no case conversions are
X performed).
X
X Prefix characters:
X
X ^ Control character prefix - The next character is made into a
X control character.
X For example: ^M = RETURN (0x0D); ^J = NEWLINE (0x0A).
X
X \ Quote prefix - The next character is transmitted verbatim. For
X example, \^ would transmit a literal ^.
X
X
XTTY ON|OFF
X
X The TTY command specifies whether or not characters received from the
X modem will be displayed on the local terminal. Since the only time that
X the script processor looks at the receive queue is during WAITFOR
X processing, the displays may look a bit erratic.
X
X Use the TTY OFF command to disable local display of received characters
X during script processing.
X
X
XWAITFOR <text> [timeout]
X
X Wait for the specified text to appear from the modem. The text argument
X should be quoted (using single or double quotes) if there are spaces to
X be transmitted.
X
X Special characters are interpreted the same as for TRANSMIT.
X
X If the timeout argument is specified, XCOMM will wait that number of
X seconds for the string to appear. If no timeout is given, XCOMM
X defaults to 30 seconds.
X
X During WAITFOR processing, characters received (up to and including the
X last character found in the text or in the timeout) can be captured to a
X disk file (if CAPTURE ON was specified), and/or displayed to the screen
X (if TTY ON was specified).
X
X
XNotes to Next Release:
X
X In the next release (2.4?), the script processor will support ALL
X command mode options, including xmodem send and receive, CIS transfers,
X local dump to terminal mode and back to script, shell commands, PUT and
X TAKE, plus a DIVERT command to transmit the contents of a data file
X through the modem (similar to the terminal mode <ESC> F command).
X
X I am always open to reasonable suggestions for improvements to the XCOMM
X program and its script language.

XI am currently working on a new release of my terminal program. It is
Xbasically a script language that is able to pump data to and from the modem.
XThe following grammar has been developed from most of the requests that I have
Xgotten.
X
XNote that this is not a formal grammar, and "yacc" is not going to be used to
Xgenerate the parser. This is basically due to the reason that yacc is a
X"compiler-compiler" and not an "interpreter-compiler".

Xgetenv()/putenv() subroutines will be used to store/retrieve user-defined
Xvariables, making them accessible to child shells. Due to their placement
Xin the environment, it is encouraged that all user-defined variables be set
Xto ALL CAPS. In addition to user-defined variables, the following variables
Xare available (but will NOT be stored in the environment):
X
X$? <-- Last shell/protocol return code
X$file <-- Current script file (- = console)
X$lineno <-- Current line number (0 console)

X
X-----
XToken values:
X
X_code <-- [a-z]*
X_file <-- [^ ]*
X_filelist <-- _file(,_file)*
X_nlstr <-- OFF | CR | LF | CRLF
X_num <-- [0-9]*
X_onoff <-- ON | OFF

X
X-----
X
XNote that statements that refer to statements (eg, "if", "while"), allow
Xstatements to be grouped as in the C programming language by using brackets {}
Xaround the block of statements.
X
X-----
XFile transfers:
X
XA new file, ".xfer" in the current or $HOME directory will be used to specify
Xfile transfer agents used within the program. Basically, each available
Xprotocol will be assigned an identifier, which will be made current using the
X"set protocol" command. File transfer agents are separately compiled programs
X(such as rz/sz) that use stdin/stdout to communicate with the remote system.
X
XValid statements within the .xfer file are:
X
Xassign _code _string <-- Assign name of an external protocol to _code
Xrfile _code _string <-- Specify the command line to receive a file
Xsfile _code _string <-- Specify the command line to transmit a file
Xrtrig _code _string <-- Set a terminal "watchfor" receive trigger
Xstrig _code _string <-- Set a terminal "watchfor" transmit trigger
X
XDuring program operation, a protocol is made current using the "set protocol
X_code" command.
X
XSpecial note regarding file transfers: The occurance of the special character
X"$" indicates the substitution of a variable. The value of the specified
Xvariable will be substitued for the variable's reference (this will not occur
Xif the "$" is quoted with a backslash). If no value of the variable is
Xavailable and the "set unattend" has not been set on, the variable's value will
Xbe requested interactively. If "set unattend" has been set on, no value will
Xbe requested, and the variable's reference will be deleted from the string.
X
XFor example, assume the following .xfer file is used:
X
X assign zmodem "Zmodem File Transfer"
X rfile zmodem "rz -y"
X sfile zmodem "sz -y $FILES"
X
XThe action from the following commands is show below:
X
X set unattend off <-- defaul value
X
X download <-- The program "rz" is executed immediately
X
X upload <-- Program does not execute "sz" immediately
X ** Enter FILES: _ <-- Value of $FILES is requested
X <-- Program "sz" is then executed
X
X assign $FILES "file.1" <-- Assigns $FILES a value
X upload <-- The program "sz" is executed immedately
X
XAlso note that when the new program is distributed, a new version of the CIS
XQuick B protocol driver will be distributed as well (under its own name). The
Xprogram will have a sample .xfer file that implements "rz/sz" and "quickb".
X
X-----
XNote that this new script language is not exactly compatible with that used in
XXCOMM 2.2. This was intentional, as more functionality was added.
X
XAlso note that this list is meant to be demonstrative and not exhaustive.
XThere are probably some tokens that are not defined, and maybe a "type-o" or
Xtwo. Basically, this is here to generate comments on things I may be missing
Xor directions I may be heading.
X
XComments regarding this document are welcome. Send comments through Compuserve
Xvia Unixforum or EASYPLEX to larry gensch at [72236,3516].

XXCOMM Command Summary
X---------------------
X
XXCOMM prompts for commands using the string:
X
X XCOMM>
X
XWith version 2.2, XCOMM supports the following commands:
X
X
Xc
X
XInitiate CIS QuickB File Transfer. This command is used for both uploading and
Xdownloading from CompuServe.
X
X
Xg file
X
XExecute the XCOMM script file "file". Returns to terminal mode when the
Xscript is complete.
X
X
Xrb file
Xrt file
X
XXMODEM receive (rb = binary mode; rt = text mode). Receive the specified
Xfile from the remote system.
X
X
Xsb file
Xst file
X
XXMODEM transmit (sb = binary mode; st = text mode). Transmit the specified
Xfile to the remote system.
X
X
Xset
X
XDisplay or set the transmission parameters used by the XCOMM program. Refer
Xto the SET section of this document.
X
X
Xt
X
XEnter terminal mode. Refer to the TERMINAL section of this document.
X
X
Xx
X
XExit program. Return to invoking program/shell.
X
X
X! <cmd>
X
XExecute the specified command as a child process. If <cmd> is ommitted,
Xexecute a local interactive shell.
X
X
X!!
X
XRe-execute the last shell command string.
X
X
X$
X
XExecute a shell command with stdin and stdout redirected to the modem port.
XThis effectively puts the computer into a "host" mode.
X
X
X%p file
X
XTransmit a file (put) to a remote Unix system. This command uses standard Unix
Xutilities on the other end.
X
X
X%t file
X
XReceive a file (take) from a remote Unix system. This command uses standard
XUnix utilities on the other end.
X
X
X?
X
XPrint a short XCOMM command summary.
X
X
X
XFile Transfers - Text and Binary Modes
X--------------------------------------
X
XWhen transferring files using the XMODEM protocol, the file mode is
Xspecified int the upload/download command. A "Text" file transfer enables
Xspecial translation of the transmitted or received file to support CP/M and
XMS-DOS end of line characters. When transmitting a file using text mode,
Xall newlines are converted to carriage-return, newline sequences. When
Xreceiving a file using text mode, all carriage-return, newline sequences are
Xconverted to a single newline. A "binary" file transfer transmits the file
X"as is" without any conversion.
X
XWhen transferring files using CompuServe QuickB protocol, the format of the
Xfile is specified by the host. An "Ascii" file will force XCOMM to perform
Xtext-mode translation; a "binary" file will turn off any translation.
X
X
XUsing the SET Command
X---------------------
X
XThe SET command is used to display and set/reset XCOMM's tunable parameters.
XThe usage is shown below:
X
X(1) set
X
X Display XCOMM's current parameters.
X
X
X(2) set 7bit
X set 8bit
X set crc
X set chk
X set term
X set cmd
X set cr
X set nl
X
X Set the indicated parameter:
X
X 7bit Modem high-bit masking. All characters received from the
X modem are masked so their values are between 0 and 127.
X This is useful for remote systems that transmit parity
X characters (the parity is ignored).
X
X 8bit Disable Modem high-bit masking. All characters received
X from the modem are displayed verbatim.
X
X crc Set XMODEM CRC protocol. All transferred blocks use a
X 16-bit block check, which is more reliable than the older
X "checksum" block check.
X
X chk Set XMODEM Checksum protocol. All transferred blocks use an
X 8-bit block check, which is not as reliable as the CRC
X block check, but is compatible with older programs using
X XMODEM.
X
X term Set auto-jumpback to terminal mode after all file transfers.
X
X cr Set newline translation mode (in terminal mode, all newlines
X will be translated to carriage returns).
X
X nl Set carriage return mode (in terminal mode, all newlines are
X sent as newlines; carriage returns are sent as carriage
X returns.)
X
X The above parameters are paired; that is, the "crc" parameter is
X negated by the "chk" parameter.
X
X XMODEM Transfers: When using "crc" protocol on a transmit, the XCOMM
X program will fall back to "checksum" block checks if the receiving
X program does not support the special "crc" handshake.

X(3) set cis on|off
X set mung on|off
X set purge on|off

X
X cis Set CompuServe <ENQ> file transfer requests. An "on" value
X specifies that when in terminal mode, an <ENQ> character
X will perform an automatic CIS QuickB protocol transfer.
X This parameter should be set "off" when not connected to
X CompuServe, as phone line noise may cause a bogus file
X transfer request.
X
X mung Set file overwrite flag. If "on", files may be overwritten
X when receiving data files. If "off", files will not be
X overwritten (will cause an error message to be displayed).
X
X purge Set Bad Telephone Line Purge mode. If "on", removes
X spurious characters received through the phone line due to
X noise before listening for an acknowledgement. This
X increases the amount of time spent transmitting each block,
X but can improve throughput overall by reducing the number of
X block retransmissions.
X
X xoff Set XON/XOFF flow control flag. If "on", the program will
X honor the XOFF control character and wait until an XON
X character is received before transmitting any more
X information. If "off", the program will ignore XOFF/XON
X requests.
X
X baud Set the desired baud rate. Supported baud rates are 300,
X 1200, 2400, 4800, and 9600 baud.
X
X cfile Set the name of the terminal mode capture file to "name".
X
X pfile Set the name of the terminal mode phonelist file to "name".

XA sample "set" command status display is shown below:
X
X Modem port is '/dev/tty00'.
X Speed is 1200 baud.
X Seven-bit communication mask enabled.
X XMODEM CRC protocol enabled.
X Extra bad telephone line purging enabled.
X Capture save file is 'capture.log'.
X Phone number file is '.phonelist'.
X XON/XOFF Flow control is OFF.
X CIS <ENQ> Auto Download is ON.
X Newline translation mode is active.
X
X
XTERMINAL Mode operation
X-----------------------
X
XIn terminal mode, all characters typed at the keyboard are sent to the
Xmodem; all characters received from the modem are displayed on the local
Xterminal screen.
X
XNewline characters (0x0A) are translated to carriage returns (0x0D) when
XNewline mode is active.
X
XWhen the ESC key is typed in terminal mode, the program will examine the
Xnext key pressed. If it is a special command function, that function will
Xbe performed; otherwise, the second character is sent to the modem. Thus,
Xto send an ESC character through the modem, it is necessary to press the
Xkey TWICE.
X
XSupported ESC commands:
X
XESC d Dial Select a phone number and dial it.
X
XESC f send File Send a file through the modem (ascii transfer). An
X option is available for waiting after each line is
X sent to avoid overrunning the remote systems input
X buffer.
X
XESC g script (GO) Execute a script file.
X
XESC h Hangup Disconnect from the remote system.
X
XESC t Toggle capture Toggle capture file - If the file is not open, it is
X opened in APPEND mode (text receive accumulates at
X the end of the file). If the file is already open,
X it is closed, instead.
X
XESC x eXit Exit terminal mode back to XCOMM command mode.

X.SH DESCRIPTION
X.LP
X\fIXcomm\fP is a public domain terminal program that currently features
X.sp
Xo XMODEM and CIS "QuickB" file transfers with optional "text" translation
X.br
Xo Hayes Modem dialing directory with BAUD and BIT parameters
X.br
Xo Unix CU compatible PUT and TAKE commands
X.br
Xo Simple HOST communication mode
X.br
Xo Communication scripting with optional linkage from phone directory.
X.LP
X\fIXcomm\fP is offerred free of charge with NO requests for financial compensation
Xreqested (this is public domain, not shareware). The source code may be
Xused or modified by anyone, but this code, or derivations of this code,
Xmay not be sold by anyone to anyone.
X.SH "COMMAND SUMMARY"
X.LP
X\fIXcomm\fP prompts for commands using the string:
X.sp
X XCOMM>
X.sp
XWith version 2.2, \fIxcomm\fP supports the following commands:
X.IP c
XInitiate CIS QuickB File Transfer. This command is used for both uploading and
Xdownloading from CompuServe.
X.IP "g file"
XExecute the \fIxcomm\fP script file "file". Returns to terminal mode when the
Xscript is complete.
X.IP "rb file"
X.IP "rt file"
XXMODEM receive (rb = binary mode; rt = text mode). Receive the specified
Xfile from the remote system.
X.IP "sb file"
X.IP "st file"
XXMODEM transmit (sb = binary mode; st = text mode). Transmit the specified
Xfile to the remote system.
X.IP set
XDisplay or set the transmission parameters used by the \fIxcomm\fP program. Refer
Xto the SET section of this document.
X.IP t
XEnter terminal mode. Refer to the TERMINAL section of this document.
X.IP x
XExit program. Return to invoking program/shell.
X.IP "! <cmd>"
XExecute the specified command as a child process. If <cmd> is ommitted,
Xexecute a local interactive shell.
X.IP "!!"
XRe-execute the last shell command string.
X.IP $
XExecute a shell command with stdin and stdout redirected to the modem port.
XThis effectively puts the computer into a "host" mode.
X.IP "%p file"
XTransmit a file (put) to a remote Unix system. This command uses standard Unix
Xutilities on the other end.
X.IP "%t file"
XReceive a file (take) from a remote Unix system. This command uses standard
XUnix utilities on the other end.
X.IP ?
XPrint a short \fIxcomm\fP command summary.
X.SH "FILE TRANSFERS - TEXT AND BINARY MODES"
X.LP
XWhen transferring files using the XMODEM protocol, the file mode is
Xspecified int the upload/download command. A "Text" file transfer enables
Xspecial translation of the transmitted or received file to support CP/M and
XMS-DOS end of line characters. When transmitting a file using text mode,
Xall newlines are converted to carriage-return, newline sequences. When
Xreceiving a file using text mode, all carriage-return, newline sequences are
Xconverted to a single newline. A "binary" file transfer transmits the file
X"as is" without any conversion.
X.LP
XWhen transferring files using CompuServe QuickB protocol, the format of the
Xfile is specified by the host. An "Ascii" file will force \fIxcomm\fP to perform
Xtext-mode translation; a "binary" file will turn off any translation.
X.SH "THE SET COMMAND"
X.LP
XThe SET command is used to display and set/reset \fIxcomm\fP's tunable parameters.
XThe usage is shown below:
X.IP (1) set
XDisplay \fIxcomm\fP's current parameters.
X.IP (2)
Xset 7bit

X.br
Xset crc
X.br
Xset chk
X.br
Xset term
X.br
Xset cmd
X.br
Xset cr
X.br
Xset nl
X.LP
XSet the indicated parameter:
X.RS +0.5i
X.IP 7bit
XModem high-bit masking. All characters received from the
Xmodem are masked so their values are between 0 and 127.
XThis is useful for remote systems that transmit parity
Xcharacters (the parity is ignored).
X.IP 8bit
XDisable Modem high-bit masking. All characters received
Xfrom the modem are displayed verbatim.
X.IP crc
XSet XMODEM CRC protocol. All transferred blocks use a
X16-bit block check, which is more reliable than the older
X"checksum" block check.
X.IP chk
XSet XMODEM Checksum protocol. All transferred blocks use an
X8-bit block check, which is not as reliable as the CRC
Xblock check, but is compatible with older programs using
XXMODEM.
X.IP term
XSet auto-jumpback to terminal mode after all file transfers.
X.IP cr
XSet newline translation mode (in terminal mode, all newlines
Xwill be translated to carriage returns).
X.IP nl
XSet carriage return mode (in terminal mode, all newlines are
Xsent as newlines; carriage returns are sent as carriage
Xreturns.)
X.LP
XThe above parameters are paired; that is, the "crc" parameter is
Xnegated by the "chk" parameter.
X.LP

Xspecifies that when in terminal mode, an <ENQ> character
Xwill perform an automatic CIS QuickB protocol transfer.
XThis parameter should be set "off" when not connected to
XCompuServe, as phone line noise may cause a bogus file
Xtransfer request.
X.IP mung
XSet file overwrite flag. If "on", files may be overwritten
Xwhen receiving data files. If "off", files will not be
Xoverwritten (will cause an error message to be displayed).
X.IP purge
XSet Bad Telephone Line Purge mode. If "on", removes
Xspurious characters received through the phone line due to
Xnoise before listening for an acknowledgement. This
Xincreases the amount of time spent transmitting each block,
Xbut can improve throughput overall by reducing the number of
Xblock retransmissions.
X.IP xoff

Xsent to avoid overrunning the remote systems input
Xbuffer.
X.IP "ESC g script (GO)"
XExecute a script file.
X.IP "ESC h Hangup"
XDisconnect from the remote system.
X.IP "ESC t Toggle capture"
XToggle capture file - If the file is not open, it is
Xopened in APPEND mode (text receive accumulates at
Xthe end of the file). If the file is already open,
Xit is closed, instead.
X.IP "ESC x eXit"
XExit terminal mode back to \fIxcomm\fP command mode.
X.SH "PHONELIST"
XThe .phonelist must exist with the file name ".phonelist" either in the
Xcurrent directory, or your home directory as defined by the $HOME
Xenvironment variable. The name of the phonelist file can be changed
Xusing the SET PFILE command.
X.LP
XThe .phonelist file is ASCII text (lines of text separated by newlines).
XIt can be created and maintained using emacs, vi, or even ed.
XThe first field of data in each line (after any whitespace and up to the
Xnext occurance of whitespace) is assumed to be a phone number in a valid
Xformat for the modem being dialed.
XAny text may follow the phone number.
X.LP
XSpecial strings within each line:
X.br
XBITS=x (x=7|8) - Set the terminal mode mask to 7/8 bits.
X.b
XrBAUD=nnnn (n=300|1200|2400|4800|9600) - Set the baud rate to the
Xspecified value
X.br
XSCRIPT=file Immediately after sending the autodial string, execute the
Xscript file specified. (Note that the specified filename is
XCASE SENSITIVE!)
X.sp
XA sample entry is shown below:
X.sp
X687-0374 CompuServe BITS=7 BAUD=1200, SCRIPT=cis.cmd
X.sp
XThe above entry indicates that the number to be dialed is 687-0374; the
Xbit mask is to be set to seven bits (ignore high bits), the baud rate is
Xto be set to 1200 baud, and commands are to be taken from the file
X"compusrv.cmd" in either the current or home directory.
X.LP
XA sample .phonelist file is included in the \fIxcomm\fP source code
Xdistribution.
X.SH "XCOMM SCRIPT LANGUAGE"
X.LP
XScript files can automate some tedious tasks such as logging into a
Xsystem. A script file is an Ascii text file and may be entered or
Xedited using any standard Unix text editor.
X.LP
XThe script file is read line by line. Empty lines (consisting of white
Xspace only) are ignored. Comments are lines whose first non-space
Xcharacter is a pound sign (#).
X.LP
XThe script processor reads each script line, ignoring leading white
Xspace, into "words". A word is defined as either:
X.sp
X- A sequence of characters delimited by white space; or
X.br
X- A sequence of characters enclosed in single or double quotes.
X.sp
X.LP
XThe first word of a script file is considered the "command word."
XIf the last character of the command word is a colon (:), the line is
Xconsidered to be a LABEL (the object of a GOTO statement). Otherwise,
Xit is assumed to be a script command and is interpreted as such.
XCommand words are case insensative.
X.LP
XSome commands take one or more arguments. Each argument is parsed as a
Xsingle word as defined above. If blanks are required in an argument,
Xthe argument MUST be quoted using single or double quotes.
X.LP
XEnclosed in the \fIxcomm\fP distribution is the file "compusrv.cmd". This is
Xan example script file (No, that is not really my user ID or my
Xpassword in that file!), and shows the use of most of the available
Xscript commands. The script commands are self explanatory for the most
Xpart.
X.SH "STARTUP SCRIPTS"
X.LP
XWhen \fIxcomm\fP is started up, it looks for the file ".xcomm" in the current
Xor $HOME directory. If it is found, it is executed. This is useful for
Xsetting your "basic" parameters without having to recompile \fIxcomm\fP. For
Xexample, your startup file may turn CIS <ENQ> mode off, set your baud
Xrate to 9600, and set 7BIT translation.
X.SH "SCRIPT COMMAND LIST"
X.IP "CAPTURE ON|OFF"
XThe command CAPTURE ON will open the capture command; all characters
Xreceived during WAITFOR processing will be appended to the capture file.
XThe command CAPTURE OFF will close the capture file.
X.br
XThis setting does NOT currently extend to terminal mode. This may be
Xoffered in a later release (probably through the SET command).
X.IP "DIAL <number>"
XDial the specified number. \fIxcomm\fP supports generic "Hayes" compatible
Xmodems for dialing. Note that this command requires an actual phone
Xnumber; the phonebook is not used for this function.
X.IP "ECHO ON|OFF"
XIf the argument to the ECHO command is ON, all subsequent command lines
Xthat are processed will be displayed on the local screen. The exception
Xto this is lines containing a TRANSMIT command. These lines will just
Xprint "TRANSMIT ...", so that passwords, etc. can be protected.
X.br
XIf the argument to the ECHO command is OFF, scripts will execute
Xquietly (this is the default setting).
X.IP EXIT
XTerminate the script file prior to the end of file. Returns to terminal
Xmode.
X.IP "GOTO <label>"
XGo to the specified label in the script file and continue execution from
Xthat point. The label may either precede or follow the actual GOTO
Xstatement.
X.IP "IF <condition>"
X.IP "<statements>"
X.IP "[ ELSE"
X.IP "statements ]"
X.IP "ENDIf"
XConditionally execute statements based on specified condition. \fIXcomm\fP
Xsupports the following conditions:
X.sp
XWAITFOR TRUE if the last WAITFOR command was successful
XLINKED TRUE if this script was executed from the phonebook
X.sp
XConditions may be negated using the prefix NOT or the character "!":
X.sp
X!WAITFOR TRUE If the last WAITFOR command timed out
XNOT WAITFOR Same as !WAITFOR above
X.sp
XThe ELSE and ENDIF keywords must appear on their own lines. IF
Xstatements may not be nested.
X.IP "PAUSE <time>"
XSuspend execution of the script for the specified number of seconds.
XThis is usually used for timing considerations; for example, waiting a
Xcouple of seconds after receiving the CONNECT message and typing ^C to
XCompuServe.
X.IP "QUIT"
XTerminate the script AND the \fIxcomm\fP program (return to the shell).
X.IP "REDIAL"
XRedial the last number dialed using the DIAL command OR the phonebook.
X.IP "SET <parameter> <value>"
XSets the specified parameter to the specified value. The SET parser
Xused in command mode is used, and the parameters/values are identical.
X.br
XDuring script processing, internal status messages are NOT displayed on
Xthe local terminal (eg, SET 7BIT ON in a script file does not display
Xthe new value on the terminal). This may be changed in the future
X(probably tied to the ECHO setting).
X.br
XDuring script processing, specifying SET alone is an ERROR... there is
Xno way currently display the current status of the SET-able parameters
Xduring script processing.
X.IP "TRANSMIT <text>"
XTransmit the specified text to the remote. The text argument should be
Xquoted (using single or double quotes) if there are spaces to be
Xtransmitted. The text is transmitted AS IS (no case conversions are
Xperformed).
X.br
XPrefix characters:
X.sp
X^ Control character prefix - The next character is made into a
Xcontrol character.
XFor example: ^M = RETURN (0x0D); ^J = NEWLINE (0x0A).
X.sp
X\ Quote prefix - The next character is transmitted verbatim. For
Xexample, \^ would transmit a literal ^.
X.IP "TTY ON|OFF"
XThe TTY command specifies whether or not characters received from the
Xmodem will be displayed on the local terminal. Since the only time that
Xthe script processor looks at the receive queue is during WAITFOR
Xprocessing, the displays may look a bit erratic.
X.br
XUse the TTY OFF command to disable local display of received characters
Xduring script processing.
X.IP "WAITFOR <text> [timeout]"
XWait for the specified text to appear from the modem. The text argument
Xshould be quoted (using single or double quotes) if there are spaces to
Xbe transmitted.
X.br
XSpecial characters are interpreted the same as for TRANSMIT.
X.br
XIf the timeout argument is specified, \fIxcomm\fP will wait that number of
Xseconds for the string to appear. If no timeout is given, \fIxcomm\fP
Xdefaults to 30 seconds.
X.br
XDuring WAITFOR processing, characters received (up to and including the
Xlast character found in the text or in the timeout) can be captured to a
Xdisk file (if CAPTURE ON was specified), and/or displayed to the screen
X(if TTY ON was specified).

Incorrect. I thought I posted on this, but maybe it didn't get
everywhere the first time...
I added HDB-style LCK files to xcomm a couple of weeks ago, but
managed to miss updating the docs before posting the source. Xcomm
respects and creates HDB-style LCK files, and can be safely installed
setuid-uucp if you wish.
BTW, I have had one report that the shars refused to unpack properly.
I can't reproduce it from the originally-posted articles on my host;
if anyone else is having such troubles, I'd appreciate a note.
Something may have become corrupted along the way.
