A researcher who also has a Comtal Vision One/20 sent me a note reading in part:

We don't have such problems here at elsie--but it's different software and
hardware (More/bsd 4.3 on an 11/750; not much on the UBA, for example, no
UDA50).  So I'll pass the question on:  has anyone out there
resolved the problems the researcher is having?  If so, or even if you're
simply have a UNIX-VAX-Comtal system, I'd appreciate hearing from you.
