COM3 and COM4 can be set to provide power to your serial device.
The voltage can be set to +5V or +12V by setting jumper JP12 on the motherboard.
When enabled, the power is available on pin 10 of the RJ45 serial connector. If you
use the serial RJ45 to DB9 adapter cable, the power is on pin 9 of the DB9 connec-
