We have a bank of Penril modems that are having a difficult time connecting
with a remote Zoom modem (unknown version).  Our Penril's are able to connect t
to other modems without problems, including the ability to "step down" to 2400
or 1200.  The Zoom modem are set to receive at 2400.  I was told that this
modem is able to connect to many other types of modems, so I think it may be
particular to this combination of modems.  
Our bank of modems is the next release after revision D. No manual.
We tried an earlier release of the Penrils, revision D, and it was able to
connect to the Zoom after several lines of garbage were recieved.  The bank of
modems display several errors being recieved and then time-out, disconnect, or
whatever after 20 seconds.  The basic configuration for the bank of Penrils
seem to be a default, however, this could be wrong.

The bank of Penrils need to dial out to many other sites.  A least common
denominator problem is rapidly evolving, it seems.

Could someone tell me:

a) Does the reciving modem initiate the discussion of what protocols are to be
used?

b) Are there any known problems with these two modems talking to each other?

c) Are there any Penril paramters i should try changing to accomodate this
problem?
