The icing on the cake is that C-Kermit can actually connect over telnet, 
so that side is also already solved. If your simh instance have a serial 
port, and it is mapped to a telnet port (something that simh supports), 
then run C-Kermit on a Unix box, and telnet into simh, and you have your 
kermit connection all set up.

If someone wants to see this in action, install C-Kermit on your 
machine, and start it. Then telnet to mim.update.uu.se (in kermit), and 
login as GUEST with password GUEST. This is not a simh instance, but no 
matter. It is an RSX system, it has Kermit-11 installed, and you are 
connected to something that looks like a serial port on that machine. 
Start Kermit-11, give the command "SERVER", and then return to C-Kermit 
prompt, and try something like DIR.

Works like a charm.
