This is a little off the subject, but perhaps you could help me:

I'm running FAS 2.08 with ISC 2.2 and it works fine for modems 
(device 208, etc.) and also for hardwired connections (device 80,
etc.). Now I want to be able to link from a dialin port to a
hardwired port connected to a BBS.

I've written a little handy-dandy that does the link OK and I can
dial in, link to the BBS and upload/download ASCII and binary OK.
The only trouble is that when the BBS hangs up, the handy-dandy
doesn't get a hangup signal.

I'm running the hardwired port as if it were modem with a cable
that connects the DTR of the BBS to the CD & DSR of the port and
have a tester on the line and can see that the CS & DSR go off
when the BBS hangs up, but no signal comes to the handy-dandy
(if I send a signal with kill -1, it hangs up OK).

When I put a PC on the hardwired "modem" port and connect to the
UNIX system, it hangs up OK, but not when I dial in and link to the
BBS on the hardwired "modem" port.

Any ideas?
