If you pull the modem out of the machine, you will see 2 jumper blocks on it - one is for port assignment and the other is for IRQ. The chart is printed on the backside of the card. You can either hardjumper the modem to a specific port and IRQ (recommended) or remove all jumpers for plug and play.
Boot into safe mode and remove ALL modems and com ports from device manager. Shut down and rejumper the modem for COM 2 IRQ 3. Go into the bios and DISABLE the second serial port (Com2, Serial B, UART2, however it's named) and make sure the first Com port is set to 3F8/IRQ4 (Com 1). Restart into Windows and Windows should install TWO com ports - Com 1 and Com 2. Go into the properties of Com 2 and set them to 115200, 8, none, 1, hardware. Go into c:\windows\inf\other and remove any INF file that says anything about 3Com or USR. Now, run the add new modem wizard and Windows should detect a modem on Com 2. If it says it's a 33.6 USR, accept it. If it says its a standard modem, change that, use Have Disk and show it the USR .inf file, and choose the correct one from the list it comes up with.
