I think you may have a Linux problem. I run Kermit 190 on a number of
Linux and SCO machines, and other than having /dev/modem be an slink to
the port so I can share scripts, I do the same thing. All my Linux
machines are 1.2.13, the latest production release.
There is always the possibility that you have a config error in Kermit,
but it's unlikely, since Kermit just doesn't work with multiple lines. I
don't suppose you've looked at the major and minor numbers with ls, and
the port config with setserial? Are the com ports configured wrong?

That's not an error, it's a design decision. You could add the lock to
your Xinitrc file if you find it needed.

It's my comm program of choice, too. I really suspect either the driver
or the hardware is configured wrong. Check the ports and ints with
setserial.
