Do you have any external serial devices, like a modem?  You could also
use another computer and place a null modem cable between them.  Then
use a command like tip(1) or minicom from the ports to connect to the
device.  What evidence leads you to believe that the serial port is bad?
You're positive that it's turned on in the BIOS?  Does dmesg reveal any
"sio" entries?
