This driver is for my 3 com modem. It is an isa 56k modem. I also include another driver that I don't use but came with my modem and the readme file. my modem is a hardware driver modem. Since I have your site now, I will continue to upload all my drivers for my sytem so other people can have it too. I know how it feels to not able to locate a driver when needed. I have a hard time finding a driver for a new mouse called Iconcepts 4D wireless optical mouse. I'm in the process of contacting the manufactures.
