Turquoise) at location CN10 for COM 1. It is also equipped with
three 9-pin connectors at locations J22, J19 and J13 for COM 2,
COM 3 and COM 4 respectively. These serial ports are RS-232
and/or RS-485 (COM 4 only) asynchronous communication ports
with 16C550A-compatible UARTs that can be used with modems,
serial printers, remote display terminals, and other serial devices.

colored stripe on the ribbon cable is aligned with pin 1 of J22, J19
or J13.
