Yes, I posted something the other day to someone about modem problems, it has
been a while, but now that I see the 'wrong baud' note, it comes back.  I had
this EXACT same problem when I first installed mine.  It turns out to be that
the baud rates in the /usr/lib/uucp/Devices file does not match that of...
uhmmmm... aw shucks! where do you spec the baud for the com port when you
just have a terminal on it??  is that one of the letters in the /etc/ttys
file config lines???

It would appear that the dialing and waiting for the CONNECT message is all 
done at the baud rate spec'd in the /usr/lib/uucp/Devices file, and that the 
baud used for the UUCP-ing is that snarffed from the /etc/ttys(?) file.  Even 
though I have my com device set to 'off' in the /etc/ttys file, I can see
that the baud and line control is gotten from there and used during the
UUCP session. (I set it to off, so there is no getty/login on it... it is a
one-way link.)

I ended up having to lock the modem baud rate, so that if I connected at a
baud rate not matching the dialed out baud rate, it would work ok.  With
respect to the MWCBBS, I have NEVER gotten a usable link to it's 2400 baud
line.  I always call their pep line (that was not answering last friday, by 
the way.)  It looks like their 2400 baud line (even from kermit) gives me
about 1 character per second at 2400 baud.  I have seen this on my ttys too
sometimes & don't have a very good handle on it yet.  Perhaps the port is
not supplying interrupts properly and it ends up running in polled mode??
