COM ports 1 & 2 have exclamation marks over them in Device Manager.
Posted on 2007-04-03
I have a PC running WIN2K and everything is working good except in System Properties/Device Manager in the list of Devices By Type, the COM port 1& 2 have a yellow exclamation mark over both and have the following messages:
COM port 1- Clicking on the COM port 1 entry in the list the General tab sez "This device is no longer functioning properly and may need to be replaced. Contact the manufacturer of this device for assistance." The port setup tab items are OK. Driver tab-Microsoft driver installed and working OK. Resources tab-I/O range 03F8-03FF, IRQ 4, no conflicts. The modem uses COM port 3 and was able to connect to the phone line and dial a number.
COM port 2- All items are the same/good as indicated above for com port 1. Resources tab shows I/O range of 02F8-02FF, IRQ 3 and no conflicts.
Why am I getting the exclamation marks and the "may not be functioning properly" message if all items appear to be OK including the fact that the modem uses com port 3 with no problem? What do I need to do to find and correct this problem?
