This is the best tried and tested driver for Motorola SM56 PCI Modem, this is not an official release, but you can never get better than this for your Motorola Sm56 PCI Modem to work with Windows XP.
I have tried and tested all versions of the Motorola SM56 PCI Modem drivers compatible with Windows XP and released by Motorola, and this one gave me the best speed <50kb/sec.> and performance!
