I am trying to write the uucico driver code for a Micom 224+ 2400/1200/300
BPS modem. I have the code working, uucico can call out to another system,
transfer data and complete the conversation, but when it tries to end the
session, it fails on the last OO syncronization. When it fails, I see
a lot of 'w's coming in. Here is the output from the end of a failed session,
note the 'w's:

Just for a reference, here is the end of a properly terminated session,
from a Concord Data Modem at 2400 baud:

The failure occurs at 1200 baud and 2400 baud, talking to a racal triple
and a Concord Data System modem respectiveley. It does not fail 100% of
the time though, sometimes the code goes through to completion. One time
at 1200 baud, I got 'U's instead of 'w's, but the result was the same. The
'w's don't start at any particular place in the transmission either.
The code can be used since it does finish the conversation before
the failure occurs, but I would prefer to have it not fail at all.
Does anyone have any hints?
