[net.dcom] Racal-Vadic VA4224

malloy@ittral.UUCP (William P. Malloy) (10/15/85)

Does anyone out there have Racal Vadic VA 4224 modems installed and running?
We currently have 3 3481's modems (actually 6, but only 3 phone lines).  Our
major USENET connection `ittatc' in CT has USR Robotics 2400's.  However we'd
like to stick to our rack mounts, thus the 4224's.  Those of you with a bunch
of normal modems stacked on top of each other, can probably appreciate why we
wish to stick with our modem rack.  (easier to use, especially for debugging)
It turned out extremely useful while getting 4.2 to talk to our modems.  The
distributed Racal-Vadic code for 4.2 just plain doesn't work.

The 4224's are rack-mounted fitting in the Racal-Vadic modem rack along with
our VA3481 (triple VA 3400, 212, 103) modems and VA831 auto-dailer.  I would
particularly like to know if someone knows if the infamous "Rockwell chip set"
problem has been fixed.  I'd also like to know how easy they are to install
if someone else has already done it.  In particular the 4224 comes WITH an
auto-dailer built-in.  Can we just ignore it and use the VA831?  If not, does
anyone know how to auto-dial them?  I.e. are they compatible with anything?

I'll send a summary of replies (if any) to anyone who's interested.  Also if we
actually get to buy these modems,  I'll let you know how the installation goes.

p.s. Interesting point.  These suckers talk (2400/1200/300) but the protocols
supported are (V.22/212/103).  Note: Vadic 3400 protocol is not supported!
