Windows 95 & 98 driver for USR X2 modem model 0460, product id # 00178700 or just 1787 as it's called on the packaging. Check your ati7 command line to see if your modem is now x2 before using this driver. This modem can be upgraded to v.90 but you have to use a different file to do so. I will upload that file (661787w.exe) in a seperate upload. This driver must be used while the modem is currently at x2 and before using the v.90 upgrade. This is a isa modem (not pci) sold around 1999.
