Hi,

I know I've got this working before, just can't remember how. Hopefully one of
you can jog my memory.

We have a Unix system (OS507) connected to a PC via their serial ports ie. COM1
to /dev/tty1a. We communicate using Kermit to send and receive files over that
3-wire cable.

Now we want to use the same cable to login to unix - I need to setup the serial
port to run a getty, but somehow disable the getty when it's time to run
communcations.

Any ideas?

many thanks

Why do you weant to disable the port? I leave my serial ports enabled at
all times, and it is never a probem to use them outbound with cu, xc,
kermit, uucp, whatever...

Yes. Don't do it. If you can log in you can transfer files. If you can't do
one you can't do the other. Do you have Kermit on the Unix box?

Maybe I'm just not remembering it properly....
So there's no need to do anything special with either serial port manager or
Specialix config - I can just run kermit on a line with a getty running?

| Yes.

I should really say:
Yes, assuming kermit is suid uucp.
