Serial Port Interface
RS-232C Port (SERIAL PORT 1, 2)
The BOX-PC has two RS-232C serial port connectors (serial port 1
designated as SERIAL1 and serial port 2 as SERIAL2). Each port
can be set up as COM1 to COM4 or as being unused by BIOS Setup
(described in Chapter 4). (Note, however, that the same COM
number cannot be assigned to different ports).
