One more detail.
Typically com1 will have a DE-9 connector soldered to the mainboard
and com2 has a 9 or 10 pin header on the board. There is more
than one arrangement of the pins of the header. If the wrong ribbon
cable from the header to the DE-9 is installed, com2 won't work.
Mentioned as a footnote to the table here.

Something to watch for on a machine which has been monkeyed with.
