Well, unfortunately we are pretty well committed to Xenix 2.2.3.  2.3.x have
unsolvable shared memory problems.  I am not sure on the exact specifics of
these problems, but it has something to do with the relational database our
software is using.  Regardless, upgrading the OS is not an option.

However, we discovered that sending the getty a SIGTERM signal when pcomm
releases the tty fixes things nicely.  Can someone explain exactly how the
silly getty routine thinks?  We found that sending it a SIGUSR1 put a DIALOUT
on the tty.  Neat stuff.  If someone has the source to any version of the
Xenix getty routines, I'd trade you my right arm, or any organ of your choice.

If anyone is running Pcomm under Xenix, you might want to fix up your port.c
routine to fix the getty on your tty after you are done.  If you only use the
port to dial out on, there is really no problem, but if you want to dial in,
you'll have to manually do a disable tty, enable tty after you are done using
pcomm, or send the getty a SIGTERM in port.c.  I'll mail anyone interested a
copy of our port.c.
