.SH "COMMAND LINE OPTIONS"
.PP
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.
.nf
.ll 80
.sp
  kermit [filename] [-x arg [-x arg]...[-yyy]..]]
.sp
where:
.sp
  filename is the name of a command file to execute,
  -x is an option requiring an argument,
  -y an option with no argument.
.ta 15
.sp
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
.sp
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)
  -J host	Connect like TELNET, exit when connection closes
  -l n	open file descriptor of TCP/IP connection (n = number)
  -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
  -8	8-bit clean

  -T	transfer files in text 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
  -Q	Quick file-transfer settings
  -w	write over files of same name, don't backup old file
  -D n	delay n seconds before sending a file
.sp
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
  -B	Force background (batch) operation
  -h	print command-line option help screen
  =	Ignore all text that follows
.sp
Remote-mode example (C-Kermit is on the far end):
.nf
.sp
  kermit -v 4 -i -s oofa.bin
.sp
.fi
sends file oofa.bin in binary mode (-i) using a window size of 4 (-v 4).
.sp
Local-mode example (C-Kermit makes the connection):
.nf
.sp
  kermit -l /dev/tty01 -b 19200 -c -r -n
.sp
.fi
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.
.sp
For dialing out, you must specify a modem type, and you might have to use a
different device name:
.nf
.sp
  kermit -m hayes -l /dev/cua -b 2400 -c -r -n
.ll
.in
.fi
.SH FILES
.nf
.ta 16
$HOME/.kermrc	Standard C-Kermit initialization commands.
$HOME/.mykermrc	Your personal C-Kermit customization file.
$HOME/.kdd	Your personal dialing directory.
$HOME/.ksd	Your personal services directory.
.fi
.PP
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, or by ftp from Columbia:
.nf
.ta 16
.sp
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.
ckermit.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.
ckepager.ksc    Alpha pager script.
.fi
.PP
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 
.IR ".kermrc" .
You should not modify
this file.
.sp
To make
.IR "personalized customizations" ,
copy the file
ckermod.ini
file to your home directory, make any desired changes, and rename it to
.IR ".mykermrc" .
.sp
You may also create a personalized
.IR "dialing directory"
like the sample one in
ckermit.kdd.
Your personalized dialing directory
should be stored in your home directory as
.IR ".kdd"
and your personal network directory as
.IR ".knd" .
See Chapters 5 and 6 of
.IR "Using C-Kermit"
for details.
.sp
And you may also create a personalized
.IR "services directory"
like the sample one in
ckermit.ksd.
Your personalized services directory should be stored in your home directory as
.IR ".ksd" .
See Chapter 7 of
.I "Using C-Kermit"
for instructions.
.sp
The demonstration files illustrate C-Kermit's script programming constructs;
they are discussed in chapters 17-19 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/ckedemo.ini".

.SH DIAGNOSTICS
The diagnostics produced by
.I 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.
.SH BUGS
See the comp.protocols.kermit.* newsgroups on Usenet for discussion, or the 
files ckcker.bwr and ckuker.bwr, for a list of bugs, hints, tips. etc.  Report
