i usually go home every weekend...when i arrived one night my mouse doesn't work anymore. i taught it was the mouse.. but when i connected my mouse to the comm2 port, it worked.

anything that i connect to my comm1 doesnt work. any suggestion?

are the COM ports integrated on the mother board or on a seperate card?

yup! its an asus motherboard. atx... just bought it last may 2002..

additional info:
when i plug a serial mouse to comm1 windows doesn't say it cannot detect a serial mouse. so that means that it had detected my mouse. but my mouse doesn't work. DOS applications doesn't detect my mouse too..

You can try to reset the BIOS setttings for the port. If there is a default or auto setting use that if not then manually set them to IRQ4 and 3F8 for address.

just an update, i reinstalled window98se yesterday. NOw it does not detect anything on the comm1.

i'll try the one suggestion. but it will be till next week before i try that.

Did you check the BIOS to make sure that Serial port 1 wasn't disabled?
If it isn't disabled in BIOS, I would assume that something has happened to the motherboard and that serial port no longer works, period. Any problems with any of the other ports (LPT, ps2, usb...)? Good luck.

i'm sure i had it all right. My comm1 just started not to function. If the defect is with the MBoard, do i have any chance of fixing it?
