Hi

How does one find which of the three subsets a given PEX server
supports? I am looking for a short program to tell me. Also, how to
tell if a server is 5.0 or 5.1

Reason I ask: we have a VAXstation here running PEX. It displays DEC
phiga apps to either an X or a PEX workstation (ie workststion types
231 or 241, for Motif).  As far as DEC PHIGS is concerned, PEX is
there and able to support server-side structures (that is, indeed, the
default). DEC PHIGS generates PEX 5.0 protocol.

We recently tried to display output from SunPHIGS 2.0 which claims to
support PEX when present. This failed with an error message which
apparently means that the PHIGS workstation subset is not present.

A demo program which came with a Tektronix XP29P PEX terminal we are
looking at also failed with the same error. This program supports 5.1
protocol.

Could someone give me a quick summary or low-down on PEX subsets, how
to get around the above problem and (preferably) why PEX has three
subsets. Is this not going to be a bit of a problem in the future?

Also could someone give me the email address of the PEX
interoperability centre as I have some other stuff I would like to
share with them.

Cheers,
