Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 61 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. SEE ALSO: Ctrl-Break key, break string parameter, zmodem B numeric parameter 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] SEE ALSO: o, off commands 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 __________ 3. Most dialing scripts include an initial bye command to make sure any previous call is disconnected. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 62 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 63 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 64 chek *.* close 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. EXAMPLE: create -ys /tmp/cbbs.tmp"*F (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 65 SEE ALSO: > command 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 66 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 67 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 "..$". (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 68 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 (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 69 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. SEE ALSO: egrepm, page commands finish Terminates Kermit server operation on the remote system. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 70 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. SEE ALSO: remote command (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 72 if condition command ... The if command provides powerful condition testing for scripts. If executes the command(s) on the rest of the line if condition is true. Otherwise, execution continues immediately with the next script line. Chapter 25 describes the testable conditions. SEE ALSO: else, on commands ife condition cmd1 ...; cmd2 ... Execute cmd1 ... if condition is true; otherwise skip to the first semicolon in the rest of the line and resume execution with cmd2. Iff a semicolon is not present, execution resumes at the end of the line, useful within the body of a while command. EXAMPLE: set f5 @ife %s1 echo "s1 =%s1"; else echo "s1 not set" 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. keys Keys displays the definitions the user has assigned to the function keys. ki Clears the y0...y127 string parameters and causes circular buffer writing operations to ignore that data from the remote which has already been displayed. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 73 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. __________ 6. Other than the dialing script (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 74 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. <keyboard the operations you wish recorded> 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 (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 75 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 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 (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 76 at the end of the string. SEE ALSO: put, putw commands 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. A bye or speed n command must be given to reassert DTR before making or answering another data call.[7] SEE ALSO: speed, bye, off commands off Disable the modem by dropping the Data Terminal Ready signal and return to DOS. A call or speedn command must be given to reassert DTR before making or answering another data call. SEE ALSO: x, o commands 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 specified file(s) 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. 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 __________ 7. Most telephone directory entries include a speed command. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 77 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 __________ 8. Pause length is specified by the q numeric parameter. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 78 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 79 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 SEE ALSO: handshake command 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 80 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 putv svar The putv command transmits svar to the remote witnout any translation of character escapes. Putv does not append a carriage return or line feed to the transmitted string. EXAMPLE: putv s0; put "\r" SEE ALSO: put, mput commands pwd Print Working Directory displays the current directory pathname, and stores it in the pwd string parameter. EXAMPLE: pwd (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 81 SEE ALSO: cd command pxN Set Numeric parameter x to value N. If x and N are blank, display the numeric parameters which can be set by this command and their current values. This command is not allowed if Restricted. Numeric parameters are described in Chapter 22. EXAMPLE: ps8 sets the status line attribute to 8 (grey), suitable for composite video displays. EXAMPLE: pv-1 sets the v numeric parameter ("verbose") to -1, suppressing some routine messages. EXAMPLE: pd1 sets the d numeric parameter to 1, causing files received with ZMODEM or full YMODEM Batch protocol to be stored with the same modification date as the source file. EXAMPLE: pk3 sets the k numeric parameter to 3, which kills pending output stored in the circulat buffer when ETX (Ctrl-C) (decimal 3) is keyboarded in the term function. r [oldcmd] Search back through the history of keyboarded lines for the first line that oldcmd is a prefix of, and execute it. If oldcmd is absent, execute the last keyboarded line. r7 [-options] [dir] [file ...] Receives with options 1 or more files using MODEM7 batch protocol. An optional disk and/or directory dir may be specified. An optional disk and/or directory dir may be specified. If pathname(s) have been supplied to the r7 command and the sending program attempts to send more files than the number of names supplied to the r7 command, the transfer is aborted. The command is provided for compatibility with traditional programs that do not support the superior YMODEM Batch or ZMODEM protocols. EXAMPLE: r7 -c SEE ALSO: MODEM7 batch protocol, Chapter 12. rb [-options] Receives with options 1 or more files using YMODEM batch protocol. The rb command also receives files sent with Clink/SEAlink protocol. Chapter 18 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 privileges are restricted, a file received in error will be unlinked (erased). (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 82 EXAMPLE: rb -y Many programs claiming to support YMODEM actually use XMODEM with 1024 byte blocks; use ZCOMM's sx -k and rx XMODEM commands with these imposters. SEE ALSO: YMODEM Batch protocol, Chapter 12. 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. CRC-16 is not the default because most IBM bulletin boards and commercial modem programs only support the 8 bit checksum. Chapter 18 describes the available options to the rc command. If privileges are restricted, a file received in error will be deleted. EXAMPLE: rc foo.com SEE ALSO: XMODEM/CRC protocol, Chapter 12. read [file] Read file into the circular buffer. Once in the buffer, it may be examined with the review command, searched for strings, and cut and pasted to other files. If file does not fit into the buffer, the buffer may be cleared with the kill command (or review k subcommand) and subsequent read commands may be given to read more of it. Review function commands are described in Chapter 21. EXAMPLE: read allsig.tmp<ENTER><Home> SEE ALSO: BROwse, seek commands CAUTION: Iff a read command has left a transmit file open, entering the term function will transmit the unread portion of the file. To prevent this, close the file first with ALT-C or closetx. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 83 receive Receives file(s) filespec from a Kermit program. remote Enter Host state with unrestricted privileges to allow the currently connected remote computer/terminal to issue commands. When activated by the remote command, Host state will reset when the modem carrier goes away. This command is useful for transferring files between two machines with directly connected serial ports. SEE ALSO: host command remote cwd dirspec [password] Instructs the remote Kermit server to change to the specified directory. The form of dirspec varies with the remote system; it must be quoted if it contains special characters or spaces. A password may be required by the remote Kermit server. SEE ALSO: Kermit Protocol, Chapter 12. remote delete filespec Instructs the remote Kermit server to delete the specified file(s). The form of filespec varies with the remote system; it must be quoted if it contains special characters or spaces. remote dir dirspec Instructs the remote Kermit server to display the specified directory on your screen. The form of dirspec varies with the remote system; it must be quoted if it contains special characters or spaces. The resulting information may be redirected to a file with the >outfile command. remote help Instructs the remote Kermit server to display help information on your screen. The resulting information may be redirected to a file with the >outfile command. remote host host-command-string Instructs the remote Kermit server to perform the specified command and display its output on your screen. The form of host-command-string varies with the remote system; it must be quoted if it contains special characters or spaces. The resulting information may be redirected to a file with the >outfile command. EXAMPLE: remote host "kill -9 0" terminates all your processes on the remote with extreme prejudice. SEE ALSO: !!command remote print filespec Instructs the remote Kermit server to print the specified file(s) on the remote system. The form of filespec varies with the remote system; it must be quoted if it contains special characters or spaces. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 84 remote space [dirspec] Instructs the remote Kermit server to display the free space in the specified directory on your screen. The form of dirspec varies with the remote system; it must be quoted if it contains special characters or spaces. The resulting information may be redirected to a file with the >outfile command. remote type filespec Instructs the remote Kermit server to type the specified file(s) on your screen. The form of filespec varies with the remote system; it must be quoted if it contains special characters or spaces. The resulting information may be redirected to a file with the >outfile command. remote who Instructs the remote Kermit server to display the logged in users on your screen. The resulting information may be redirected to a file with the >outfile command. reset Write the contents of the circular buffer if a receive file is open, close all files, and reset the disk system. This allows swapping diskettes. reskeys Resets the Soft Keys to empty. SEE ALSO: set command RETurn Returns from a script subroutine accessed by a call, source, or gosub command. SEE ALSO: fail command rewind Reset the buffer pointers for display, printer, and file output used by the term function to the beginning of the circular buffer. This will cause the term function to redisplay the data in the circular buffer. Patterns will be rescanned. A typical use of the rewind function is to allow replay of an editing session on a remote machine, or to redisplay the material received if the initial settings of the i, c, n or v modes were incorrect for the material received from the remote. NOTE: The rewind command does not reset the buffer free character count. To write the data to disk, a write command (or ALT-W) must be given before accepting new data from the remote. SEE ALSO: t, b, w review subcommands REView Review the data received from the host or read by the read command. A screenfull is displayed at a time. Review function commands are listed in Chapter 21. ro [-options] file Receives with options a single file using non- standard XMODEM-CRC protocol logic. OverThruster(TM) speeds file downloads at the expense of error recovery. OverThruster operation is controlled by the O numeric parameter (q.v.). As fans of (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 85 Buckaroo Bonzai know, the OverThruster is not universally applicable. A transmission error will almost always terminate an OverThruster file download. If Restricted, a file received in error will be unlinked (erased). EXAMPLE: ro foo.com SEE ALSO: O numeric parameter rt [-options] [dir] [file ...] Receives with options 1 or more files using Telink (FIDO) 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 pathname(s) have been supplied to the rt command and the sending program attempts to send more files than the number of names supplied to the rt command, the transfer is aborted. The rt command is provided for compatibility with traditional programs that do not support the superior YMODEM Batch or ZMODEM protocols. EXAMPLE: rt -c SEE ALSO: Telink protocol, Chapter 12. rw [-options] file Receives with options a single file using the experimental People-Link WXMODEM protocol. Chapter 18 describes the available options. If restricted, a file received in error will be unlinked (erased). EXAMPLE: rw foo.com rx [-options] file Receives with options a single file using the Ward Christensen XMODEM protocol. Chapter 18 describes the available options. If restricted, a file received in error will be unlinked (erased). EXAMPLE: rx foo.com NOTE: The rc command should be used whenever possible instead of rx. SEE ALSO: XMODEM protocol, Chapter 12. rz [-options] Receives with options 1 or more files using ZMODEM batch protocol. Chapter 18 describes the available options. Each file's pathname is obtained from the sending program. The +, a, b, n, N, r, and y options are accepted from the sending program, subject to (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 86 restriced privileges. If the +, b, n, N, r, or y option is specified to the receiver, it overrides any contrary options specified to the sender. Only one of the a, b, or r options may be specified. Only one of the +, n, N, or y options may be specified. If a file is received in error (retries exhausted, etc.), the batch transfer will terminate. If privileges are restricted, a file received in error will be unlinked (erased). EXAMPLE: rz -y SEE ALSO: Z mode SEE ALSO: ZMODEM protocol, Chapter 12. rz [-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 rz command, the transfer is aborted. To allow use of the rz command, Z mode (ZMODEM autodownload) should be turned off with a dis -Z command. s Displays status information. LSR and MSR refer to the Line Status Register and Modem Status Register of the selected port 8250 UART device. If one or more scripts are active, the current line number (counting from the first line in the script file) for each script level is displayed. s7 [-options] pathspec Send the files specified in pathspec using the MODEM7 batch Protocol. 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 an error aborts a file transmission (retries exhausted, etc.), batch transfers terminate. EXAMPLE: s7 *.com sends *.com NOTE The receiver must be commanded to receive the files. This command is provided for compatibility with traditional programs that do not support the superior YMODEM Batch and ZMODEM protocols. SEE ALSO: MODEM7 batch protocol, Chapter 12. sb [-options] pathspec Send the files specified in pathspec using the YMODEM Batch Protocol.[9] The pathname, length, and modification (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 87 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 an error aborts a file transmission (retries exhausted, etc.), batch transfers terminate. The sb command will send files with Clink/SEAlink protocol if the receiving program requests Clink. EXAMPLE: sb -k *.com sends *.com using 1024 byte packets. NOTE The receiver must be commanded to receive the files with an rb or rz command. SEE ALSO: YMODEM Batch protocol, Chapter 12, Clink protocol, Chapter 12. seek offset Iff a transmit file is open as a result of a f, open, or read command, position the file read pointer to offset bytes from the beginning of the file if offset is positive (or 0), or from the end of the file if offest is negative. "Seek 0" rewinds the file to its beginning. EXAMPLE: open baz; seek -20000; read<ENTER>Home reviews the last 20000 bytes of baz. SEE ALSO: open, read, close send pathspec Send the specified files with the Kermit protocol. The send command sends files to either a Kermit server or a regular Kermit program. set[s|c|n|?] [[_]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 _f1 "logout\r" assigns the string "logout<ENTER>" to F1 until the next call command. ______________________________________________________________________ 9. The receiver may trigger transmssion with the ZMODEM protocol zcommand command. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 88 The parameters that may be set with this command are described in Chapter 23. 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 24 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 Keys. EXAMPLE: sets s8 "S9 EQUALS %s9" substitutes the value of string parameter s9 in the argument before assigning it to s8. SEE ALSO: echo, if, keys, ALT-K, commands NOTE: 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. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 89 The setn command stores a decimal number of an arithmetic expression consisting of decimal numbers, string variables, the length of atring variables denoted with %, and the oprators +, -, *, and /. The expression is exaluated strictly left to right. EXAMPLE: setn vv 1+vv The set? command stores a decimal number representing the result of a test condition. EXAMPLE: set? speed S stores the value of the S test condition (transmission speed) in string variable speed. set[s|c] [_]sparam 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 is handy 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. NOTE: 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. 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 more put commands to login to a timesharing service. The presence of a character in the keyboard buffer will cause the sleep to command to finish at once. The maximum sleep time is 32000 tenths of seconds. Applications involving long sleep times may be better handled with the Host Operation callout queue. __________ 9. Because a failed if command would skip to the next line, the argument of the set command, and attempt to execute it as a script line. (C) 1987 Omen Tech Inc Chapter 17 Main Commands Revised 09-05-87 Universal Line Printer Edition ZCOMM User Manual 90 EXAMPLE: sleep 30 pauses for 3 seconds. SEE ALSO: b numeric parameter Soft Keys The Soft Keys F5-F40, Ins, Del, Home, End, Up, Down, Left, Right, PgUp, and PgDn may be programmed with commands by set commands given in script files, including the "setup" entry in the distribution PHODIR.T file. The commands assigned to these keys may be displayed with the keys or ALT-K command. source sourcefile Accept script commands from sourcefile. The source and call commands may be nested with up to six[10] scripts open at once. 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. SEE ALSO: gosub command 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 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 __________ 10. Deep nesting may require a decrease in circular buffer memory allocation.
