Serial Port Stopped Working

I have a modem serial device connected to my host server and it is being used bya Windows 2003 guest. The modem stopped working after a power bump the other day.

I have tried another modem and that is not working. I have verified that the guest is set to connect to the serial port at boot. As I said, this configuration had been working fine for months until before the power bump. I am thinking the com port is toast on the Dell PowerEdge 6500 host. How do i test this? Preferably without taking the host down. The host is ESX 3.0.


Thanks in advance!

You will likely need to take the host down and run the Dell diagnostic tools.  If you have had no software/hardware changes, you are probably right that the power hit took out the port.  Unfortunately we often forget to put surge protection on the phone lines.  (I have lost several modems and serial ports.)
