[comp.dcom.modems] 9600bps modem compatibility question

ejd@caen.engin.umich.edu (Edward J Driscoll) (03/02/90)

I haven't had much experience with 9600 bps modems -- the extent
of my knowledge is knowing what most of the lights mean.  We use
Racal-Vadic 9600VP's here, which don't seem to be compatible
with other 9600bps modems.  Someone else here needs a new 9600bps
modem for his PC to connect with the New York office, where they
use 9600bps Hayes modems.  I'm also looking at putting our 3B2
on the net at some point down the road, and expect to find that
I will need a TBIT for that.  

In a nutshell, which 9600 bps modems are compatible with which
other ones?  What are the rules governing compatibility?

(which 9600 baud modem?)

You want v.32 compatibility if you want to escape vendor dependencies.
Note that Merit is not providing 9600 baud dial-in access as well
with v.32s.

Otherwise you need the same brand at either end (modulo a few
exceptions).
