NAME

kermit - C-Kermit 5A(190) communications software for serial and network connections: modem dialing, file transfer and management, terminal connection, character-set translation, and script programming.

SYNOPSIS

kermit [ command-file ] [ options ... ]

DESCRIPTION

Kermit is a family of file transfer, management, and communication software programs from Columbia University available for most computers and operating systems. The UNIX version of Kermit, called C-Kermit", supports serial connections (direct or dialed) and, in most UNIX implementations, also TCP/IP connections. On SunOS systems equipped with SunLink X.25, C-Kermit can also make X.25 connections. C-Kermit can be thought of as a user-friendly and powerful alternative to cu, tip, uucp, ftp, and telnet; a single package for both network and serial communications, offering automation, convenience, and language features not found in the other packages, and having a great deal in common with its cousins, C-Kermit on other UNIX platforms, MS-DOS Kermit for PCs with DOS and Windows, and IBM Mainframe Kermit-370 for VM/CMS, MVS/TSO, and CICS. C-Kermit itself also runs on OS/2, Digital VMS, Data General AOS/VS, Stratus VOS, OS-9, Apollo Aegis, the Apple Macintosh, Commodore Amiga, and the Atari ST. Together, C-Kermit, MS-DOS Kermit, and IBM Mainframe Kermit offer a consistent and nearly universal approach to inter-computer communications.

The C-Kermit software may not be, in whole or in part, licensed or sold for profit as a software product itself, nor may it be included in or distributed with commercial products or otherwise distributed by commercial concerns to their clients or customers without written permission of the Office of Kermit Development and Distribution, Columbia University. This copyright notice must not be removed, altered, or obscured.

C-Kermit is thoroughly documented in the book Using C-Kermit by Frank da Cruz and Christine M. Gianone, Digital Press, 1993; see REFERENCES at the end of this manual page. New features added since the book was published are documented in the online file ckcker.upd". Hints, tips, limitations, restrictions are listed in ckcker.bwr (general C-Kermit) and ckuker.bwr (UNIX-specific); see FILES below. Please consult all of these references before reporting problems or asking for technical support.

Kermit software is available for hundreds of different computers and operating systems from Columbia University. For best file-transfer results, please use C-Kermit in conjunction with real Columbia University Kermit software on other computers, such as MS-DOS Kermit for DOS or Windows. See CONTACTS below.


MODES OF OPERATION

C-Kermit can be used in two "modes": remote and local. In remote mode", you connect to the UNIX system from a desktop PC, Macintosh, or workstation and transfer files between your desktop computer and UNIX C-Kermit. In that case, connection establishment (dialing, TELNET connection, etc) is handled by the Kermit program on your desktop computer.

In local mode", C-Kermit establishes a connection to another computer by direct serial connection, by dialing a modem, or by making a network connection. When used in local mode, C-Kermit gives you a terminal connection to the remote computer, using your actual terminal, emulator, or UNIX workstation terminal window or console driver for specific terminal emulation.

C-Kermit also has two types of commands: the familiar UNIX-style command-line options, and an interactive dialog with a prompt. Command-line options give you access to a small but useful subset of C-Kermit's features for terminal connection and file transfer, plus the ability to pipe files into or out of Kermit for transfer.

Interactive commands give you access to dialing, script programming, character-set translation, and, in general, detailed control and display of all C-Kermit's features. Interactive commands can also be collected into command files or macros.


STARTING C-KERMIT

C-Kermit should be available as "kermit" somewhere in your PATH, perhaps as /usr/local/bin/kermit, in which case you can start C-Kermit just by typing "kermit", possibly followed by command-line options. If there are no "action options" on the command line (explained below), C-Kermit starts in interactive command mode; you will see a greeting message and then the "C-Kermit>" prompt. If you do include action options on the command line, C-Kermit takes the indicated actions and then exits directly back to UNIX. Either way, C-Kermit executes the commands in its initialization file, .kermrc, in your home directory (or a system-wide directory if C-Kermit was built to do this) before it executes any other commands, unless you have included the ` \c -Y\c ' (uppercase) command-line option, which means to skip the initialization file, or you have included the ` \c -y filename\c ' option to specify an alternative initialization file.


FILE TRANSFER

Here is the most common scenario for Kermit file transfer. Many other methods are possible, most of them more convenient, but this basic method should work in all cases.

¤ Start Kermit on your local computer and establish a connection to the remote computer. If C-Kermit is on your local computer, use the sequence SET MODEM modem-name\c , SET LINE device-name\c , SET SPEED bits-per-second\c , and DIAL phone-number if you are dialing; SET LINE and SPEED for direct connections; SET NETWORK network-type and SET HOST host-name-or-address for network connections. ¤ SET any other necessary communication parameters, such as PARITY, DUPLEX, and FLOW-CONTROL. ¤ Give the CONNECT command. ¤ Log in to the remote computer. ¤ Start Kermit on the remote computer, give it any desired SET commands for file-, communication-, or protocol-related parameters. If you will be transferring binary files, give the command SET FILE TYPE BINARY to the remote Kermit program. ¤ To download a file or file group, give the remote Kermit a SEND command, following by a filename or "wildcard" file specification, for example:


  send oofa.txt            (send one file)

or:

  send oofa.*              (send a group of files)

To upload a file or files, give the remote Kermit a RECEIVE command. The sending Kermit will tell the receiving Kermit the name (and other attributes) of each file. ¤ Escape back to the Kermit program on your local (desktop) computer. If your local computer is running C-Kermit, type Ctrl-\ c (Control-backslash followed by the letter 'c') (on NeXT workstations, use Ctrl-] c). If MS-DOS or OS/2 Kermit, use Alt-x (hold down the Alt key, press 'x'). Now you should see your local Kermit program's prompt. ¤ If you will be transferring binary files, give the command SET FILE TYPE BINARY to your local Kermit program. ¤ If you are downloading files, tell the local Kermit program to RECEIVE. If you are uploading", give your local Kermit program a SEND command, specifying a filename or wildcard file specification. In other words, tell the remote Kermit program what to do first, SEND or RECEIVE, then escape back to the local Kermit and give it the opposite command, RECEIVE or SEND. ¤ When you finish transferring files, give a CONNECT command. Now you are talking to Kermit on the remote computer again. Type EXIT to get back to the command prompt on the remote computer. When you are finished using the remote computer, log out and then (if necessary) escape back to Kermit on your local computer. Then you can make another connection or EXIT from the local Kermit program.

C-Kermit's file transfer protocol defaults are deliberately conservative, resulting in file transfer that almost always works, but might be somewhat slow. To increase file transfer performance on computers and connections that permit it, use SET RECEIVE PACKET-LENGTH to increase the packet length, SET WINDOW to increase the window size, and use SET CONTROL UNPREFIX to reduce the overhead of control-character prefixing. On serial connections, use hardware flow control (SET FLOW RTS/CTS) if available, rather than software (XON/XOFF) flow control. On TCP/IP connections, SET FLOW NONE. For details, read Chapter 8 of Using C-Kermit and see the section on control-character unprefixing in the ckcker.upd file.


OTHER FEATURES

C-Kermit includes features too numerous to be explained in a man page. For further information about connection establishment, modem dialing, networks, terminal connection, key mapping, logging, file transfer options and features, troubleshooting, client/server operation, character-set translation during terminal connection and file transfer, "raw" up- and downloading of files, macro construction, script programming, convenience features, and shortcuts, plus a command reference, numerous tables, examples, and illustrations, please consult Using C-Kermit".

HELP

C-Kermit has extensive built-in help. You can find out what commands exist by typing ? at the C-Kermit> prompt. You can type HELP at the C-Kermit> prompt for "getting-started" message, or HELP followed by the name of a particular command for information about that command, for example:


  help send

or:

  help set file

You can type ? anywhere within a command to get brief help about the current command field. You can also type the INTRO command to get a brief introduction to C-Kermit, and the NEWS command to find out what's new in your version. Finally, you can use the BUG command to learn how to report bugs.

ENTERING COMMANDS

You can use upper or lower case for interactive-mode commands, but remember that UNIX filenames are case-sensitive. You can abbreviate commands as long as the abbreviation matches only one possibility. While typing a command, you can use the following editing characters:

  Delete, Backspace, or Rubout erases the rightmost character.
  Ctrl-W erases the rightmost "word".
  Ctrl-U erases the current command line.
  Ctrl-R redisplays the current command.
  Ctrl-P recalls a previous command (scrolls back in command buffer).
  Ctrl-N scrolls forward in a scrolled-back command buffer.
  Ctrl-C cancels the current command.
  Tab, Esc, or Ctrl-I tries to complete the current keyword or filename.
  ? gives help about the current field.

To enter the command and make it execute, press the Return or Enter key.

BACKSLASH NOTATION

Within an interactive command, the "\" character (backslash) is a prefix used to enter special quantities, including ordinary characters that would otherwise be illegal. At the end of a line, \ or - (dash) makes the next line a continuation of the current line. Other than that, the character following the \ identifies what the special quantity is:

  % A user-defined simple (scalar) variable such as \%a or \%1
  & an array reference such as \a[3]
  $ an environment variable such as \$(TERM)
  v (or V) a built-in variable such as \v(time)
  f (or F) a function such as \Fsubstring(\%a,3,2)
  d (or D) a decimal (base 10) number (1 to 3 digits, 0..255) such as \d27
  o (or O) an octal (base 8) number (1 to 3 digits, 0..377) such as \o33
  x (or X) a hexadecimal (base 16) number (2 digits, 00..ff) like \x1b
  \ the backslash character itself
  b (or B) the BREAK signal (OUTPUT command only)
  l (or L) a Long BREAK signal (OUTPUT only)
  a decimal digit (a 1-3 digit decimal number) such as \27
  {} used for grouping, e.g. \{27}123
  anything else: following character taken literally.

Note that numbers turn into the character with that binary code (0-255), so you can use \7 for a bell, \13 for carriage return, \10 for linefeed. For example, to have C-Kermit send a BELL to your screen, type:

  echo \7

COMMAND LINE OPTIONS

C-Kermit accepts commands (or "options") on the command line, in the time-honored UNIX style. Alphabetic case is significant. All options are optional. If one or more action options are included, Kermit exits immediately after executing the command-line options, otherwise it enters interactive command mode.



  kermit [filename] [-x arg [-x arg]...[-yyy]..]]

where:

  filename is the name of a command file to execute,
  -x is an option requiring an argument,
  -y an option with no argument.


Actions:
  -s files	send files
  -s -	send files from stdin
  -r	receive files
  -k	receive files to stdout
  -x	enter server mode
  -f	finish remote server
  -g files	get remote files from server (quote wildcards)
  -a name	alternate file name, used with -s, -r, -g
  -c	connect (before file transfer), used with -l or -j
  -n	connect (after file transfer), used with -l or -j

Settings:
  -l line	communication line device (to make a serial connection)
  -l n	open file descriptor of communication device
  -j host	TCP/IP network host name (to make a network connection)
  -l n	open file descriptor of TCP/IP connection
  -X	X.25 network address
  -Z	open file descriptor of X.25 connection
  -o n	X.25 closed user group call info
  -u	X.25 reverse-charge call
  -q	quiet during file transfer
  -i	transfer files in binary mode
  -b bps	serial line speed, e.g. 1200
  -m name	modem type, e.g. hayes
  -p x	parity, x = e,o,m,s, or n
  -t	half duplex, xon handshake
  -e n	receive packet-length
  -v n	window size
  -w	write over files of same name, don't backup old file
  -D n	delay n seconds before sending a file

Other:
  -y name	alternate init file name
  -Y	Skip init file
  -R	Advise C-Kermit it will be used only in remote mode
  -d	log debug info to file debug.log
  -S	Stay, don't exit, after action command
  -C "cmds"	Interactive-mode commands, comma-separated
  -z	Force foreground operation
  -h	print command-line option help screen
  =	Ignore all text that follows

Remote-mode example (C-Kermit is on the far end):


  kermit -v 4 -i -s oofa.bin

sends file oofa.bin in binary mode (-i) using a window size of 4 (-v 4). Local-mode example (C-Kermit makes the connection):

  kermit -l /dev/tty01 -b 19200 -c -r -n

makes a 19200-bps direct connection out through /dev/tty01, CONNECTs (-c) so you can log in and, presumably start a remote Kermit program and tell it to send a file, then it RECEIVEs the file (-r), then it CONNECTs back (-n) so you can finish up and log out. For dialing out, you must specify a modem type, and you might have to use a different device name:

  kermit -m hayes -l /dev/cua -b 2400 -c -r -n

$HOME/.ksd	Your personal services directory.

The following should be in a publicly accessible plain-text documentation area, such as usr/local/lib/kermit, /usr/local/doc, or /usr/share/lib/kermit, or available via an information server such as gopher:



ckaaaa.hlp      Explanation of C-Kermit files.
ckermit.ini     Standard initialization file.
ckermod.ini	Sample C-Kermit customization file.
ckermit.kdd	Sample dialing directory.
ckermit.ksd	Sample services directory.
ckcker.upd	Supplement to "Using C-Kermit".
ckcker.bwr	C-Kermit "beware" file - hints & tips.
ckuker.bwr	UNIX-specific beware file.
ckedemo.ini     Demonstration macros from "Using C-Kermit".
ckevt.ini       Ditto.
cketest.ini     Ditto.

If C-Kermit has not been installed on your system with the system-wide initialization file feature, then the ckermit.ini file should be copied to your home (login) directory and renamed to .kermrc. You should not modify this file. To make personalized customizations, copy the file ckermod.ini file to your home directory, make any desired changes, and rename it to .mykermrc. You may also create a personalized dialing directory like the sample one in ckermit.kdd. Your personalized dialing directory should be stored in your home directory as .kdd. See Chapter 3 of Using C-Kermit for details. And you may also create a personalized services directory like the sample one in ckermit.ksd. Your personalized services directory should be stored in your home directory as .ksd. See Chapter 13 of Using C-Kermit for instructions. The demonstration files illustrate C-Kermit's script programming constructs; they are discussed in chapters 11-13 of the book. You can run them by typing the appropriate TAKE command at the C-Kermit> prompt, for example: "take /usr/share/lib/kermit/cketest.ini".

DIAGNOSTICS

The diagnostics produced by C-Kermit itself are intended to be self-explanatory. In addition, every command returns a SUCCESS or FAILURE status that can be tested by IF FAILURE or IF SUCCESS. In addition, the program itself returns an exit status code of 0 upon successful operation or nonzero if any of various operations failed.
