Internal Modem on Xenix 386

[Don Glover]

I set up my Xenix 386 system and had some problem getting my internal
modem to respond, found out that I had to set up the devices file 
so got that going and things seemed to be fine.  Now I set up a terminal
on com1  and my internal modem is com2 and I cannot get the modem to answer
in coming calls anymore, cu will not access it to do out going calls.
the only change I have made is to setup to use the com1 with a terminal.
Any ideas out there as to what I may messed up unkowingly?
