Well, this must have sounded like a stupid question to all of you when
you first read it. Mike Raffety <mike_raffety@il.us.swissbank.com> was
the only person to respond. The HSI/S is a synchronous device. What I
was trying to do was for an async port. When I mention that I might have
to get an SPC he added:
> Do *NOT* buy the Sun SPC card! It's crap ... buy the Magma card, much
> better, in general opinion, not just my own.

Does everyone pretty much agree on this point?
Thanks Mike.
For completeness here is the original query and respondent credits:
