I have been able to duplicate this problem across a rather large
variation in ttys and modems, so I must conclude it's uugetty that
is getting wedged. I have an AT 386 clone running AT&T 386 UNIX.
The first problem I had was getting a COM2 board to work with the USR
Courier 24 modem (worked fine on COM1), so I plugged in a Zoom 2400XL
internal. It worked OK but from time to time it would answer the
phone and never prompt for login. That's the worst of bad manners
because all of ssbn's neighbors call LD on their nickel. I attributed
the problem to the Zoom and eagerly awaited the driver from Computone
for the Intelliport AT-4 I had. When I got that I switched to one of
the ttys on the AT-4 and set up the USR but the problem persisted (along
with some new ones I won't bore you with. Yesterday I got an AT class
dual serial card (I had been using an XT version before) and figured I
had it whipped.
From time to time uugetty just forgets to look for characters to start
a session. I can always recover by killing the uugetty but that is not
an acceptable solution with the system virtually unattended. It's a
pain in the neck when the system is attended. Since the problem persists
across ttys and modems I want to blame uugetty. Any thoughts?
I have a brute force solution and that is to have the other modem call
the USR from time to time and kill the uugetty if the login fails. I
am very doubtful of my ability to construct such a script and I'm afraid
that I'll kill the wrong one or do something else that will wedge the
whole system. My inittab line reads
I01:1234:respawn:/usr/lib/uucp/uugetty -r -t15 -d tty00 9600M
I02:1234:respawn:/usr/lib/uucp/uugetty -r -t15 -d tty01 2400H
The -d is a relic from my PC 6300 PLUS, for some unexplained and undocumented
reason it worked better with the -d. The -t15 is to make for a prompt on-hook
if the login isn't going to work rather than linger through a minute which
might cost the caller another minute of LD.
Any help is much appreciated, nobody likes a rude neighbor and I particularly
dislike being the one that's being rude. Thanks!
