This zip file comes from BTC Corp. Copy it onto a 1.4 floppy,open it,leave it in the a drive,go to control panel,modems, and remove your modem,shut down the computer, and reboot. If it doesn't automatically see the driver then you can point it to the a drive. I am to understand that there has been no updates from the manufacturer of your modem but this company makes an identical one and your modem is actually based on it's design...this is BTC's upgraded driver and it may serve your needs. Good luck.
