With the 20.16MHz Couriers and Sportsters, adding S27=48 to your dialling
string will solve this problem by disabling the V.42 detect phase, and
forcing a LAPM connect.  The newer Sportsters/Dynalinks have had their
S-registers remapped, and whilst I'm fairly sure that S15=128 performs the
same function, I'd suggest that you check with Tom Przeor, just to be on
the safe side. 

BTW, according to USR's Tech Support fellows, the actual cause of this
problem is a faulty implementation of V.42 in some Rockwell chipset-based
modems.
