I've heard there are quite a few problems with modem drivers under XP. The MS Gensoft driver chosen by XP just produced a "no dial tone" error message in my case. I then tried to install the Windows 2000 driver for a Diamond SupraExpress 56i Pro modem (which both Microsoft and Diamond say should work), but the installation routine just went round in a loop without installing the driver. Can't get a straight answer from Diamond as to when their proper XP driver will be available. Anyone managed to get this particular modem up and running under XP?
