Actually, we have run into the same problem with USR Sportster 28.8's. I
myself have talked with some of the top tech's at USR, and the reason the
USR's tend to hang up with other modems is because of their compression
method. USR uses a propriatary compression method that when connected
with a modem that has the rockwell chipset, will hang up. It is a VERY
easy situation to make re-occur. It has been tested with MANY different
modems on MANY different phone lines. I do not understand why USR would
continue to use such a compression method. Anyways, we are forced to
tell our customers who use USR 28.8 modem's to add to thier init string a
&k0 which will turn off compression.
