(Contributed) My hardware - IBM Thinkpad 760ED - built in IR hardware 'PNP0510' WIN95 - PC Remote works fine - sets up the built-in IR hardware as a 'Generic IR Serial Port' and assigns a COM port WIN98 - PC Remote does not work under the enhanced IrDa support - sets up the built-in IR hardware with devices for: - 'Network adapter' - Virtual COM and PRT ports - IrDa Modifications: What I did was disable the enhanced IrDa support for the built-in IR hardware on my Thinkpad and re-enabled the older WIN95 'Generic IR' support so that WIN98 would view the IR hardware as a Serial Port and assign a true COM port that PC Remote could find. In the file: C:\Windows\inf\Msports.inf make the following two changes . . . [Std] %*PNP0400.DeviceDesc% = LptPort, *PNP0400 ; Printer Port %*PNP0401.DeviceDesc% = EcpPort, *PNP0401 ; ECP Printer Port %*PNP0500.DeviceDesc% = ComPort, *PNP0500 ; Communications Port %*PNP0501.DeviceDesc% = ComPort, *PNP0501 ; Communications Port ; ;Add the following line to support the Thinkpad 760 IR port %*PNP0510.DeviceDesc% = ComPort, *PNP0510 ; Generic IR device/Comm Port . . . . [Strings] MS = "Microsoft" Std = "(Standard port types)" PortsClassName = "Ports (COM & LPT)" *PNP0400.DeviceDesc = "Printer Port" *PNP0401.DeviceDesc = "ECP Printer Port" *PNP0500.DeviceDesc = "Communications Port" *PNP0501.DeviceDesc = "Communications Port" ; ;Add the following line to provide a device description for PNP0510 *PNP0510.DeviceDesc = "Generic Ir Serial Port" Once these two changes are done, then go into Device Mgr and remove the devices associated with the original WIN98 configuration: - IrDa Network Adapter - Virtual COM/PRT ports - Infrared device Reboot the Thinkpad - Windows should now install a 'Generic Ir Serial Port' and assign a true COM port. ** You may also need the IBM Thinkpad 760 Infrared Device Driver files before it works properly - this is available from IBM's Website (www.ibm.com).
