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!
