This is a slightly lobotomized kermit. Because of bugs in
cc and limitations in asld, I had to remove the help command, the
script facility, and the automatic dial support. ? and ESC still
work, so there's still reasonable builtin help. This is based on the
normal Unix version of kermit, in a configuration very similar to v7.
The only feature in v7 that I couldn't make work is the ability to see
whether there are input characters waiting. This means that you won't
be able to ask for status while a file transfer is happening (though
this isn't critical, because kermit prints a dot every so often and
other special characters whenever there is an error or timeout).
Simple instructions on use:
Run kermit, and then type
set line /dev/tty1
set speed 2400
connect
(It's more convenient if you put these commands in .kermrc in your
home directory, so that they get done automatically whenever you
run kermit.) This will connect you to the modem or whatever on
the serial port. Now log into the other system.
When you want to transfer files, run kermit on the other system.
To it, type
server
This puts its kermit into a sort of "slave mode" where it expects
commands from the kermit running on your Minix system. Now come back
to the command level on Minix kermit, by typing the escape character
followed "c". (kermit will tell you the current escape character when
you do the connect command.) At this point you can issue various
commands. Your kermit will coordinate things with kermit on the other
machine so that you only have to type commands at one end. Common
commands are
get filename
put filename
remote dir
Filenames can include wildcards. By default, kermit works in a
system-independent, text mode. (In effect it assumes that the
whole world is MS-DOS and converts end of line and file names
accordingly.) To send binary files, you will want to type
set file type bin
on both ends before starting any transfers. This disables
CR LF to newline conversion. If both of your systems are some
flavor of Unix, you might as well put this in .kermrc on both
ends and run in binary mode all the time. Also, if both systems
are Unix I recommend
set file name lit
on both ends. This causes it to keep file names unchanged,
rather than mapping to legal MS-DOS names.
Here's the .kermrc I use on minix:
set file type bin
set file name lit
set rec pack 1000
set esc 29
set prompt Minix Kermit>
connect
set rec pack 1000 says to request 1000-byte packets when receiving
files. (This will be ignored if the other end doesn't support
long packets.) This makes line utilization more efficient than
the default 100-byte packets, though it isn't critical. (You may
not want to do this unless you have installed my changes to
increase buffer sizes, though on a 10MHz AT, 1000-byte packets
work even without the patch as long as you are using a disk rather
than a floppy.)
set esc 29 sets the escape character to ^]. No particular reason.
I just like that characters.
I change the prompt since the other end is normally a Unix system.
If I don't change one or the other, both ends will prompt
C Kermit>
which is sort of confusing.
Here's the .kermrc I use on our Unix hosts:
set rec packet 1000
set fil name lit
set fil type bin
server
