Disable MNP10 with #K0. Also, USR support advised me to turn off V.42 and
V.42bis at the Rockwell end as they say the most usual problem is failure
in V.42/b negotiation phase.

 LE>> M34F I tested (this was a 6682-21 datapump)...
 db> Do all M34F's have the same datapump?  I keep hearing about
"old" and

Nope. In approx. Feb 1995, Rockwell released the R6682-26 (DSP code 05BA).
Type AT#V0I6 on your M34F and you'll see a dump which includes a line
something like "Rockwell Controller Revision" and a 4-digit hex
number in quotes. "04BC" is the old R6682-21, "05BA" is
the newer R6682-26. NetComm had huge stocks of the -21, and were continuing
to ship -21 modems for a long time after the -26 became available. Ask
Maestro, Zoom, Boca, GVC, Zoltrix, Askey, and a dozen other people with
vested interests, and you'll hear an official statement "The only
technical difference, to our knowledge, is improved cellular protocol
support". This is garbage, as the observable results are that there
are several internal DSP code bugfixes. The -26 is far more stable than the
-21.
