We use a Hayes Smartmodem 1200 on our Vax 750 running 4.2BSD.
We have always had a fairly high dialup failure rate.  Finally
I decided to investigate and put extra checks in the hysopn()
routine.

I discovered that under certain conditions the read of the Hayes result
byte fails with an error 5 (EIO).  This seems to happen most often
after the previous dialup in the uucico loop got a busy line or
other failure.  The dial command write immediately before the read
works perfectly.  All subsequent dialing operations in the same
invocation of uucico also fail for the same reason (but the writes
always work damnit).

I am continuing to investigate.  In the meantime has anyone else seen
anything like this?
