Rockwell HCF: from what I have seen, Rockwell's will only work if you
disable V.90. Disabling V.90 fixes most of the problems with these
modems.
Cirrus Logic: These modems will not connect whatsoever.
SoundBlaster Modems: Update the drivers, they work fine.
SupraMax modems: Disable V.90, work fine.
I'm in Waco, so you all can conclude that we're not up to specs... damned
