Here is a function that will let you know if the COM port is disabled in
CMOS...
To see if the COM ports are even recognized in DOS, use the following
routine:
1) From a DOS command line, type "Debug".
2) Type "e 40:0"
You should receive a "F8".
3) Press the Spacebar once and the results should be "3". This is the
address to COM1, 03F8.
If you get nothing but zeros, or 02F8, (COM2's address), then COM1
isn't accessible in DOS.
4) Keep hitting the Spacebar to step through the addresses for the
remaining COM ports. You should receive the following:
"f8", then "2": COM2.
"E8", then "3": COM3.
"E8", then "2": COM4.
