perhaps the modem doesnt work, have you tried it in another machine ? i would uninstall both com1 and com2 (as well as any other com ports) from device manager. i would reboot the computer with the isa modem jumper set at irq3 2f8-2ff. reboot, see if it will find it. or run Regedit, goto hkey_current_config, system, currentcontrolset, enum, and look for a key relating to the modem and delete it, then try to install it again.
