[comp.dcom.modems] USR and other V.32bis -downward compatibility with V.22

gklaass@yunexus.yorku.ca (Gary Klaassen) (03/24/91)

I have some literature on
the US Robotics V.32bis modem which says that it is compatible with
V.32bis at 14.4, 12.0, 9.6, 7.2 and 4.8 Kbps, and V.32 at 9.6 and 4.8 Kbps.
It says absolutely nothing about compatibility with V.22 or V.22bis
at 2400 baud.  Does anyone know if the USR V.32bis  modem or any other V.32bis
modems can communicate with 2400 baud V.22/V.22bis modems?  I tried the
USR hotline, but have been playing phone tag for a week. Thanks
