[comp.dcom.telecom] ROLM Data Network Auto-answer Problem

paha@uhura.cc.rochester.edu (Philip Harriman) (07/26/90)

Executive summary:  

I am looking for help with auto-answer programs (such as Procomm
Plus's host mode, Carbon Copy, etc.) working with a ROLM data network.
I have learned of a disk from ROLM, Model #43096A, which contains a
patch to fix the problems I am experiencing, and I am trying to get
this disk from ROLM.  While I wait (rather impatiently), I'd like to
hear from others who might have experienced this problem, any
solutions they have found, and a copy of the patch.

Background:

Here at the University of Rochester we have a ROLM digital voice and
data telephone system.  While the switch-over from our old analog
telephone system to the ROLM switch was being planned, we were all
told that our analog modems would no longer work, but that the ROLM
switch would be better, including outbound and inbound modem service.
ROLM was installed, but things are not all great.  We have experienced
problems with auto-answer telecommunications packages, like Procomm
Plus's host mode and Carbon Copy, which have the ability to answer an
incoming call.  These packages expect to find a Hayes-compatible modem
sitting at their COM port, not a ROLM switch.  When I put Procomm Plus
into host mode, it sets DTR high.  This has the effect of getting the
attention of the ROLM switch, which responds with its prompt, "CALL,
DISPLAY, OR MODIFY ?"  This is interpreted by Procomm as someone
trying to log in, and mass confusion results.

Request:

We would really like to be able to dial into our PCs, either from
other offices on campus or from off-campus using the in-bound modem
pool.  As mentioned above, I am waiting for a patch disk from ROLM
which claims to fix this problem.  I was wondering if anyone out there
has experienced similar problems, has found a solution, and could
possibly send me the patch (I have low hopes of getting it through
other channels).

Please send email direct to me; I will summarize to the net.

Thanks!
