The only problem with this is that uuchat is a routine which periodically
is hung up on the port.  Like this morning, we looked in and we had
not logged into uunet last night.  Sure enough, uuchat was active on
the port, and I did a manual kill, and everything went like fine.

Is there something generic here that many of us are doing wrong?
We have a T18PC (Telebit) internal modem and use a couple of
simple scripts to write info to the modem.

We connect to systems at 2400 and at 19200.
Thanks for any input.
