How does a 10-pin motherboard header translate to a 25 pin parallel
port?

Because it's morning, i didn't word it right to say that it's only the
rs-232 that's 10 pins. The parallel one has more. I added a DB-9
rs-232
and an lpt port to my pc using a cable and back-connectors from an old
junk pc. Motherboard is a P5E-V HDMI.
One caution: there are two different pinouts used for 10 pin
asynchronous serial ports on PC motherboards and serial cards. Only
one uses an easy ribbon cable connection from DB9 to 10-pin header.
IIRC the other literally used pin 1 to 1, 2 to 2, 3 to 3 ... and had
to have each line hand connected to the DB9 or DB25.
