I'm gonna do some guessing here...you didnt tell us what serial port you were trying to connect the modem to!! Do you have a serial mouse? If you have a PS2 style mouse then you want to connect the modem to Serial Port(Com 1) and turn it on...If you have Win 98 it will probably find it and allow you to install drivers...If you have Win 95 you need to read instructions that came with modem on how to install it on Com 1. If you DO HAVE A SERIAL MOUSE....it's gonna get a LOT harder, but it is doable. Just let us know a bit more about your system so we can come up with what it will take to get your modem working. Keep in mind, you want to be sure there are NO "?"'s in Control Panel/System/Device Manager prior to trying this install.
