That's a little surprising considering there is a standard for the serial port pinout.  It was a one-to-one mapping.  Pin one of the header went to pin one of the D-shell connector.  Pin 10 was to be blank and used as a polarity key with a matching plug in the connector hole.

However, I had the same experience with a motherboard using a USB header.  It is five pins and is normally set up as Power, Data Minus, Data Plus, and Ground.  This one motherboard has some weird arrangement that I have yet to figure out because one port works and the other doesn't.  I'll have to probe it some more next time I open it to see if I can get both ports functional.
