Modem woes (3b1, AT&T 2224)

[Bob Wilber]

I'm having problems getting an AT&T 2224 modem to work with the 3b1.  When I
try to use it with the AT&T command set at 2400 baud (all switches down except
SW 5 is up) it keeps autobauding down to 1200 baud.  Since the modem at the
other end is at 2400 baud, garbage results.  I tried sending an initial BREAK
but that doesn't help.

I have a bit more luck in Hayes ("AT command set") mode, since I can call out
at 2400 baud and get a connection, without my modem reverting to 1200 baud.
However, when I leave cu the modem never hangs up.  I have to hit the DATA
button on the modem.  This inability to hang up will do bad things to my phone
bill if uucp tries dialing out.

I'm using HDB uucp, in case that matters.

Does anyone know how to get this modem to work?
