ISTR having to mod our 3780 COMBOARD code to talk to a Series/1 in
about 1992 or so because someone in WI bought our VAXBI COMBOARD to
send EDI purchase reqs to a vendor network run by IBM and the device
on the other end of our customer's modem was a Series/1 that didn't
quite exactly implement 3780 like all the IBM products before it.
