TP General - Red X by serial port in Device Manager
Applicable to: World-Wide
SYMPTOM
Red X by Serial Port in Windows 95 Device Manager
CONFIGURATION
Any ThinkPad running Windows 95
SOLUTION
Serial Port disabled in ThinkPad Features. Do not be concerned if you see a Red X by a Serial Port in the Windows 95 Device Manager. This simply means that the port is disabled in the current configuration. By default, the external serial port is disabled in ThinkPad Setup, but it's presence is still detected by Windows 95. If you need to use the external serial port, use ThinkPad Setup to disable either the Infrared, ( or the DSP Modem if you have a system with Mwave) and then enable the external serial port. Then restart Windows 95 and you will be able to add the port to your current configuration using Device Manager.
NOTE:
In order to avoid possible hardware conflicts, ThinkPad Setup requires that you either disable the Infrared Device, change the Infrared IRQ, or disable the Mwave DSP Modem on MWave equipped systems before you can enable the external serial port. The Mwave DSP Modem may still be enabled in Windows 95, even if disabled in ThinkPad Setup.
