or to disable the serial port.
Settings for this option are:
COM1 (the default) — Maps the serial port to
COM1
COM2 — Maps the serial port to COM2
COM3 — Maps the serial port to COM3
COM4 — Maps the serial port to COM4
Disabled — Disables the serial port and its
assigned COM address, freeing that interrupt for
another device to use
For a change in the Serial Port option to take
effect, you must reboot your computer.
