Folks, I'm sure many folks here have this attitude about PCI modems in general. I think I know why: the chipset implementation leaves much to be desired. The 3Com/US Robotics Winmodems are notoriously bad for its subpar performance--which soured a lot of people on PCI modems in general. Fortunately, I did find a few that do work great. I'm right now testing a Best Data Model 56HP PCI modem that uses the Convexent (neé Rockwell) chipset--and I was most pleasantly surprised by its excellent performance. In fact, it is actually faster in some ways than my Zoom Telephonics Model 2949L V.90 external modem! I think it's a case that the Convexent chipset works very well on the PCI interface and the fact the Windows 9X/ME/2000/XP drivers work very well for this modem.
