OVERVIEW

MS-DOS Kermit is a communication software program that performs two primary
functions: terminal emulation and file transfer.  In order to communicate at
all, your PC must have a communication device (serial port, internal modem, or
network interface) which is connected to a modem, the phone system, or a
network.

Then Kermit must be told what communication device to use.  In the most common
case, this is a serial port, perhaps with an external modem attached.  If
Kermit is using a serial port and/or modem, it must be told which port (SET
PORT 1, SET PORT 2, etc), what the communication speed is (SET SPEED), and
depending on the type of connection and the type of host, possibly many other
communication parameters as well (SET DUPLEX, SET PARITY, SET FLOW-CONTROL,
and so on).  For networks, it must be told which kind of network interface
and/or protocol to use (SET PORT NETBIOS, SET PORT NOVELL, SET PORT DECNET,
SET PORT 3COM, etc).

For terminal emulation, you must tell Kermit which kind of terminal to emulate
(SET TERMINAL).  Kermit emulates the DEC VT320 terminal by default (i.e.
unless you tell it otherwise).

Once you have set all the appropriate communication parameters, you can begin
terminal emulation by giving the CONNECT command.  If you have an autodial
modem, you must type the modem's dialing commands to establish the connection
to the other computer.  You can return to Kermit by typing the "escape
sequence", Ctrl-] followed by the letter C (or you can use Alt-X on IBM
keyboards).

To transfer files, you must CONNECT to the other computer, login there,
start up a Kermit program, tell it to SEND or RECEIVE, escape back to MS-DOS
Kermit, and tell it to RECEIVE or SEND (the opposite of what you told the
other Kermit).  Or you can put the remote Kermit in "server mode" by giving it
the SERVER command, and then escape back to MS-DOS Kermit and give SEND and
GET commands.

Here's an example, which uses a Hayes modem for dialing, and a Kermit server
on the remote computer.  "C>" is the DOS prompt, "MS-Kermit>" is the MS-DOS
Kermit program prompt, "$" is the remote host prompt.  All commands except
Alt-X are terminated by pressing the Enter key.  Alt-X means hold down the Alt
key and press the X key.  Don't type the comments on the right.

MS-DOS KERMIT PROGRAM INVOCATION

MS-DOS Kermit can be run interactively, from a batch file, as an "external"
DOS command, or with redirected or piped standard input and output.  Upon
initial startup, the program executes any commands found in the file
MSKERMIT.INI in the current disk or DOS path, or the file specified by "-f
filename" on the Kermit command line.

* Interactive Operation:

To run MS-DOS Kermit interactively, invoke the program from DOS command level
by typing its name, usually "kermit".  When you see the command's prompt,
"MS-Kermit>", you may type Kermit commands repeatedly until you are ready to
exit the program.  The commands EXIT or QUIT return you to DOS.

While typing commands, use the Backspace key to erase the character most
recently typed, Ctrl-W to delete the most recent field, or Ctrl-U to delete
the entire command, and enter the command by pressing the Enter key or Ctrl-L.
A question marked typed at any point in a command (except in a filename or
character string) will give you a brief hint about what's expected at that
point.  Pushing the Esc key will complete the command current field, if
possible, and position the cursor at the next field.  If completion is not
possible, Kermit will beep.  You can cancel any command during its execution
by typing Ctrl-C.

Use question mark (?) to "feel" your way through commands and find out what
the options are.

* Command Line Invocation:

MS-DOS Kermit may be invoked with command line arguments from DOS command
level, for instance:

  A>kermit set port 1, set speed 9600, connect

In this case, help and completion are not available and MS-DOS Kermit will
exit back to DOS after completing the specified commands unless you include
the STAY command.  Several commands may be given on the command line,
separated by commas.

* Batch Operation:

Like other MS-DOS programs, MS-DOS Kermit may be operated under batch with
command line arguments.  If your batch program invokes Kermit without command
line arguments it will run interactively, reading commands from the keyboard
and not the batch file.  When it exits, batch processing will continue to the
end of the batch file.  An ERRLEVEL number is returned by Kermit to assist
batch file controls (0 = success, nonzero = at least one file transfer failed).

* DOS Environment for MS-DOS Kermit:

Make sure your DOS PATH variable (as set by the PATH= line in your
AUTOEXEC.BAT file) includes the disk and directory where the Kermit program
and the MSKERMIT.INI file are kept.

Kermit will search for a DOS environment variable named KERMIT, and configure
itself accordingly.  You can this variable by putting a line like this in your
AUTOEXEC.BAT file:

  SET KERMIT=command;command;...

The commands can be:

  INPUT-BUFFER <length> - Length of buffer for INPUT command, 128 by default.
  ROLLBACK <number> - Number of screens for rollback (PgUp), 10 by default.

Example:

  SET KERMIT=INPUT-BUFFER 1000;ROLLBACK 100

Kermit also looks in the DOS environment for COMSPEC and SHELL, and uses the
program denoted by SHELL= (if found, otherwise by COMSPEC=) when executing
the PUSH, RUN, TYPE, and similar commands.

Kermit is capable of having many files open at once (several TAKE files, a
file which is being transferred, up to three log files, etc).  You should
make sure the FILES= line in CONFIG.SYS allows for at least 20 open files.
You should also have a BUFFERS= value of about 20 in CONFIG.SYS.

SUMMARY OF MS-DOS KERMIT COMMANDS

* MS-DOS Kermit 3.0 in Non-DOS Environments: 

MS-DOS Kermit 3.0 can run under Microsoft Windows 2.03 and Windows 386 2.03 as
a regular MS-Windows application (icon, mouse, cut-&-paste, etc).  Files can
be transferred while other applications are active, as long as Kermit has a
piece of the screen (has not shrunk to an icon).  Install the KERMIT.PIF file
from the Kermit distribution disk with your other MS-Windows PIF files and
Kermit will start up as a normal-looking Windows application.  Without the
.PIF file, Kermit will take over the whole screen (and will run faster, and
will be able to use graphics).

MS-DOS Kermit 3.0 can run under OS/2 in the "DOS box", provided you first
issue the command SETCOM40 COM1=ON.

Reports on DesqView, Concurrent DOS, etc, are not yet in for 3.0.

  see below for local area nets).  You can also say SET PORT 1, SET PORT 2, etc
SET PORT {BIOS1, BIOS2, etc}
  Use BIOS-level driver for COM1, COM2, etc, rather than built-in code.
  Allows Kermit to be used with nonstandard devices.  Also see section on
  local area networks below.
SET SPEED <number>
  Communications port line speed: 1200, 2400, 9600, etc.  SET SPEED ? for list.
  As of version 3.01, the "split speed" 75/1200 is also available.
SET PARITY {EVEN, ODD, MARK, SPACE, NONE} = NONE
  Character parity to use during communication.  If not NONE, then 8th-bit
  quoting is used during file transfer.
SET DISPLAY { 7, 8 } = 7
  Use 7 for stripping off parity bit, e.g. with UNIX systems.
  Use 8 for 8-bit international character sets.
SET DUPLEX {FULL, HALF} = FULL
  Select full or half duplex communication.
  FULL = remote echo.  HALF = local echo plus RTS/CTS hardware handshake.
SET HANDSHAKE {NONE, XON, CR, LF, CODE <ascii-value>} = NONE
  Half-duplex line turnaround character (XON is most common).
SET FLOW-CONTROL {XON/XOFF, NONE} = XON/XOFF
  Select full-duplex flow control method.
SET TERMINAL {VT320, VT102, VT52, HEATH-19, TEK4010} = VT320
  Select type of terminal to emulate.
SET TERMINAL CHARACTER-SET { LATIN1, DEC-MCS, GERMAN, FRENCH, etc } = LATIN1
  Tell Kermit what character set is used by the host computer during terminal
  emulation.  Received characters are translated from this set into the
  current PC code page.  Characters that you type are translated from current
  PC code page to this set.  LATIN1 is ISO Latin Alphabet 1 (an 8-bit set).
  GERMAN, FRENCH, etc, are 7-bit National Replacement Character sets (NRCs).
  Use SET KEY and SET TRANSLATION INPUT to override Kermit's built-in
  character translations on an individual basis, and SET TERMINAL
  CHARACTER-SET TRANSPARENT to disable them altogether.
SET TERMINAL ?
  Many other terminal parameters: color, tabstops, wrap, etc.
CONNECT
  Make a terminal connection to another computer on the currently selected
  port using the current communication settings.  Use Alt-X to return
  ("escape back") to the MS-Kermit> prompt (hold down the Alt key and press x),
  Raises DTR.  Can abbreviate as C.
HANGUP
  Hang up a dialed modem connection by lowering DTR.
SET DEBUG SESSION
  Turn off terminal emulator, display received characters literally for
  debugging: ^X = Ctrl-X, ~X = X with 8th bit on.
SET DEBUG OFF
  Turn off session debugging.

* Local Area Networks

SET PORT NETBIOS
  Tells Kermit to use IBM Netbios rather than serial communication port.
  Tells MS-DOS Kermit to await connections from other PCs on the net.
  Also used with AT&T StarLAN/StarGroup.
SET PORT NETBIOS <name>
  Tells Kermit to connect to another PC on the Netbios network.  Also for
  AT&T StarLAN/StarGroup.
SET PORT NOVELL
  For using Novell network asynchronous communication servers (NASI/NACS).
  (see below).
SET PORT DECNET [<node> [<password>]]
  For DECnet-DOS LAT or CTERM connections.  Specify node to connect to, LAT
  password if required. 
SET PORT UB-NET1
  For Ungermann-Bass Net/One.
SET PORT OPENNET [<node>]
  For Intel OpenNET, similar to Netbios.
SET PORT 3COM
  For using 3COM BAPI asynchronous communication server, BRIDGE PCS or 3+OPEN
  TCP versions.
SET PORT { BIOS1, BIOS2, BIOS3, BIOS4 }
  For using any network that operates through a BIOS-level COM port driver.
  Examples include Novell TES (see below), IBM EBIOS, 3COM BAPI (old BRIDGE
  PCS version only), TCP/IP Telnet (e.g. through Interlan TCP/IP Novell
  Gateway, or FTP Software TC/TCP Jan 1990 version 2.04 pl 1).
HANGUP
  Close network connection, terminate network session.

MS-DOS Kermit 3.0 can operate with Novell products in at least three ways:
with the NASI/NACS asynchronous server, with NetWare/VMS via the TES.COM
utility from Novell, and with NetWare File Servers.

1. NASI/NACS.  Install NACS on a Novell async server and install NASI on a
workstation (perhaps by loading it from a file server), both according to
Novell's instructions.  Start the client network shell and then start NASI.
Run Kermit, use SET KEY to attach keyboard verb \Knethold to a key (for
example "SET KEY \1374 \Knethold" to assign it to Ctrl-F1), and give Kermit
the commands SET PORT NOVELL and then CONNECT. The NASI menu screen should
appear, or push Enter to make it appear.  Select an async port and NASI/NACS
will make an initial attachment to that port.  Futher NASI/NACS commands are
available by pressing the key for \Knethold while in CONNECT mode.  The Kermit
command HANGUP will close and terminate the current connection.  Once a
connection is running Kermit can be used in file transfer, CONNECT (terminal
emulation), and script modes.

2. TES.  Start the client network shell.  Ensure a VAX/VMS system is operating
on the network as a NetWare File Server.  Run TES.  TES installs itself as a
Terminate Stay Resident (TSR) program until you give the DOS command TES
UNLOAD.  Next run Kermit and give the commands SET PORT BIOS1 and CONNECT.
Press the TES hot keys, usually ALT-Left-Shift-T, and the TES menu will
appear.  Select a machine for connection and press the ESC key.  A VMS login
prompt should appear.  The TES connection will be maintained until you log out
of VMS or the Kermit HANGUP command has been given.  Multiple connections are
possible by using the TES hot key and placing the current one on hold.  Be
aware that VMS command TYPE filename can cause TES to be overwhelmed by the
VAX if the file is especially long.  Once a connection is running Kermit can
be used in file transfer, CONNECT (terminal emulation) and script modes.

3. File Servers.  This is especially easy because the file server disk drive
letters work naturally with Kermit.  Special procedures are designed into
Kermit to assist printing to a network printer while Kermit is attached to a
host via a high speed communications port.  Network printing is achieved by
using the Novell utility CAPTURE to redirect the first PC printer channel to
the file server.  Kermit uses the file server the same way you do: as an
additional set of disk drive letters and/or as extra printers.


* CONNECT-Mode Escape-Level Commands:

During terminal emulation, you may type Ctrl-] (hold down Ctrl and press the
rightbracket key) followed by any of the following characters:

  ?   Help -- prints the available single-character commands
  0   (the digit zero) Transmit a NUL (ASCII 0)
  B   Transmit a BREAK signal                                 (also Alt-B)
  C   Close the connection and return to Kermit prompt level  (also Alt-X)
  F   File the current screen in the screen dump file         (also Ctrl-End)
  H   Hangup the phone (or network connection)
  L   Transmit a Long Break (1.8 seconds)
  M   Toggle the mode line, i.e. turn it off if it is on & vice versa
  P   Push to DOS; get back to CONNECT by typing EXIT at the DOS prompt
  Q   Temporarily quit logging the remote session
  R   Resume logging the remote session
  S   Show the status of the connection
  ^]  (or whatever you have set the escape character to be)
      Typing the escape character twice sends one copy of it to the host

You may use SET ESCAPE to change the escape character from Ctrl-Rightbracket
to some other character, or you can use the Alt-key equivalents noted above
on the IBM keyboard, or you can use SET KEY to assign \Kexit or other
"Kermit verbs" to the keys of your choice.  \Kexit is also assigned to Alt-X
on IBM keyboards.

* SET TRANSLATE INPUT Command:

  SET TRANSLATE ON
  SET TRANSLATE INPUT <code1> <code2>

Specifies that when a character represented by <code1> arrives at the
communication port during terminal emulation, it should be translated into
<code2> before display on the screen.  Overrides current terminal character
set translation for that character.  Translations set up in this way take
effect only after you give the command SET TRANSLATE INPUT ON, and you can
disable (and restore the default translations) with SET TRANSLATE INPUT OFF.
SET TRANSLATE INPUT ON/OFF does not affect the built-in translation between
terminal character set and PC code page.  To disable the latter, use SET
TERMINAL CHARACTER-SET TRANSPARENT.

* SET KEY Command:

  SET KEY <scancode> <value>

Assigns <value> to the key whose scan code is given.  When you press the key
or key combination that corresponds to the scan code during terminal
emulation, the <value> is transmitted out the communication port.  If you
don't know the scan code, type SET KEY alone on a line, then press the desired
key or key combination when prompted, then enter the definition.  The <value>
can be a single character, a text string (which may contain backslash codes),
or one or more Kermit verbs.  SET KEY overrides the default translation for
the given key.

* Commonly Used Kermit Verbs (default assignment in parens):

\Kexit        Exit from connect mode (Alt-X, Ctrl-]C)
\Kbreak       Send a BREAK signal (Alt-B, Ctrl-]B)
\Kdos         Push to DOS (Ctrl-]P)
\Kdump        Dump current screen to file (Ctrl-]F)
\Khangup      Hangup communication port connection (Ctrl-]H)
\Klogoff      Stop session logging (Ctrl-]Q)
\Klogon       Resume session logging (Ctrl-]R)
\Kmodeline    Toggle mode line off/on++ (keypad minus)
\Kprtscn      Print current screen (Print Screen)
\Kreset       Reset terminal emulator (Alt-=)
\Ktermtype    Change terminal type (Alt-minus)
\Kupscn       Roll back screen (PgUp)
\Kupone       Roll back screen one line (Ctrl-PgUp)
\Kdnscn       Roll screen forward (PgDn)
\Kdnscn       Roll screen forward one line (Ctrl-PgDn)
\KterminalR   Execute macro named TERMINALR if any
\KterminalS   Execute macro named TERMINALS if any
\Knethold     Put a network connection on hold, select another one

Use SET KEY to assign or reassign these verbs to the keys of your choice.
Example: "SET KEY \315 \Kexit" puts \Kexit on the F1 key.

* Commands for Transferring Files:

SEND <filename> [<alternate-name>]
  Send files to remote Kermit receiver or server.  Can abbreviate as S.
RECEIVE [<filename>]
  Wait for a file to arrive from the other Kermit program, which must

  text file.  Default is your current PC code page.  Kermit translates between
  the current file character set and the transfer character set during file
  transfer.
SET TRANSFER CHARACTER-SET { TRANSPARENT, LATIN1 } = TRANSPARENT
  Tell Kermit which character set to use when sending and receiving Kermit
  packets.  TRANSPARENT means no translation.  LATIN1 is ISO Latin Alphabet 1,
  useful for transferring text that contains accented characters with other
  Kermit programs that support this feature. 
SET FILE WARNING { ON, OFF, NO-SUPERSEDE } = ON
  What to do when a file arrives that has the same name as an existing file.
  ON = Automatically give the arriving file a unique name.
  OFF = Overwrite the existing file with the new file.
  NO-SUPERSEDE = Reject any file that has the same name as an existing file.
SET INCOMPLETE { KEEP, DISCARD } = DISCARD
  What to do with a file that does not arrive completely.
SET RETRY <number> = 5
  How many times to retry a particular packet before giving up on the file.
SET TIMER { ON, OFF } = ON
  Enable/Disable timeouts and retransmissions during file transfer.
SET WINDOW <num> = 1
  Number of sliding window packet slots.  Sizes greater than 1 can be used
  only with other Kermit programs that supports sliding windows.  Improves
  transmission efficiency on long-delay connections.
SET SEND (or RECEIVE) <parameter> <value>
  START-OF-PACKET <num> = 1  packet begin character, normally Ctrl-A
  END-OF-PACKET <num> = 13   packet end character, normally carriage return
  PACKET-LENGTH <num> = 94   packet length; 2000 max; > 94 is "long packets"
  PAUSE <num> = 0            Interpacket pause, milliseconds
  TIMEOUT <num> = 5          Timeout interval waiting for a packet, seconds
  PADDING <num> = 0          How many padding characters before each packet
  PADCHAR <num> = 0          Padding character to use

Use SHOW FILE, SHOW PROTOCOL to examine current file transfer settings.

* Commands for Unguarded File Transfer:

TRANSMIT <filename>
  Send a text file to the host as if you were typing it at the keyboard.
SET TRANSMIT <parameter> <value>
  Various parameters used to control TRANSMIT command (SET TRANSM ? for list).
LOG SESSION <filename>
  Capture a remote file, which you must TYPE, into the named file.

* Commands for Recording:

LOG TRANSACTION [<filename>] = TRANSACT.LOG
  Log file transfer names, times, etc, in given file.
LOG SESSION [<filename>] = SESSION.LOG
  Record terminal session in given file.
LOG PACKETS [<filename>] = PACKET.LOG
  Record file transfer packets in given file
WRITE {PACKET,SESSION,TRANSACTION,SCREEN} {DATE,TIME,PATH,TEXT,etc} [<text>]
  Write the given quantity to the specified log file or to the screen.
CLOSE {PACKET, SESSION, TRANSACTION, ALL}
  Close the specified log file and stop logging.
REPLAY <filespec>
  Display a session log, running it through the terminal emulator.
SHOW LOG
  Display names and status of logging and log files.

* Macros and Variables:

DEFINE <name> [<value>]
  Defines a macro called "<name>" to have the given value.  If <value> omitted,
  undefines the name.  Value may be a list of MS-DOS Kermit commands,
  separated by commas.  Can also be used to define a variable like \%1,\%a,etc.
[DO] <name> [<parameter1> [<parameter2> [<parameter3> [...]]]]
  Executes the macro called "<name>", and assigns the parameters, if any,
  to the variables \%1, \%2, \%3, etc, and sets the variable ARGC to the
  number of parameters plus one (1 = no parameters, 2 = 1 parameter, etc).
ASSIGN <variable1> <variable2>
  Copies the current value of <variable2> into <variable1>.
SHOW MACRO [<name>]
  Shows the definition of the specified macro or variable.
IF DEFINED <name> <command>
  Executes the <command> if the <name> is defined.
IF = ARGC <num> <command>
  Executes <command> if ARGC is equal to <num> (numeric constant or variable)
IF < ARGC <num> <command>
  Executes <command> if ARGC is less than <num>
IF > ARGC <num> <command>
  Executes <command> if ARGC greater than <num>
IF NOT > ARGC <num> <command>
  Executes <command> if ARGC less than or equal to <num>
IF =, <, >
  Can also be used with any numeric variable, not just ARGC, including the
  other predefined numeric variables, VERSION, COUNT, and ERRORLEVEL, or
  any other variable (such as \%1, \%a) that has a numeric value.  Use
  IF EQUAL to compare character strings (see below).

* Script commands:

INPUT [<timeout>] <string>
  Wait up to <timeout> secs for <string> to arrive at communication port.
  If it arrives, set SUCCESS.  If not, time out and set FAILURE.
  String may contain backslash codes.
OUTPUT <string>
  Send the <string> out the communication port.
SET INPUT CASE { IGNORE, OBSERVE } = IGNORE
  Say whether alphabet case should matter in searching for INPUT string.
SET INPUT DEFAULT-TIMEOUT <secs> = 1
  Timeout interval to use if none given in INPUT command.
SET INPUT ECHO { ON, OFF } = ON
  Whether to display characters read by INPUT command on the screen.
SET INPUT TIMEOUT-ACTION { PROCEED, QUIT } = PROCEED
  PROCEED means set SUCCESS or FAILURE and go on to next statement in macro
  definition or TAKE file.  QUIT means to quit from current macro or TAKE
  file immediately upon timeout (i.e. upon failure).
IF SUCCESS <command>
  Execute the <command> if the preceding INPUT command succeeded.  Also works
  with file transfer commands like SEND, RECEIVE, GET, BYE, etc.
IF FAILURE <command>
  Execute the <command> if the preceding INPUT or file transfer command failed.
PAUSE <secs>
  Do nothing for specified number of seconds, or until any character is typed
  at the keyboard.  Raises DTR.
WAIT [<timeout>] [\DTR] [\CD] [\CTS]
  Wait <timeout> (seconds or until time hh:mm:ss) for specified modem signals.
  Raises DTR.
CLEAR
  Clear communication port input buffer.
STOP
  Return from macro or TAKE file to the MS-Kermit> prompt.
POP
  Return from current macro or TAKE file to the macro, TAKE file which
  invoked it, or if none, to the MS-Kermit> prompt.
GOTO <label>
  Instead of executing the next statement in the current macro definition or
  TAKE-file, go to the specified label and begin executing there.  The label 
  must be a word that begins with a colon (:) in the left margin in the
  current macro definition or TAKE file.
:LOOP
  The previous line shows a label called "loop".  GOTO LOOP would find it.
REINPUT [<timeout>] <string>
  Like INPUT, but instead of waiting for <string> to arrive at communication
  port, REINPUT rescans the text that has already arrived.
SET COUNT <num>
  Sets the loop counter to <num>.
IF COUNT <command>
  Subtract one from count.  If result > 0, execute <command>.
  Use with GOTO to construct counted loops.
SET ALARM <time>
  Set an alarm <time> seconds from now, or at time hh:mm:ss.
IF ALARM <command>
  If the alarm time has passed, execute the <command>.
SET ERRORLEVEL <number>
  Set errorlevel to be returned to DOS by Kermit upon exit.    
IF ERRORLEVEL <number> <command>
  If errorlevel of most recently executed DOS command matches or exceeds
  <number>, execute the <command>.
IF EXIST <filename> <command>
  If the named file exists, execute the <command>.
ASK <variable> <prompt>
