    Have you checked 'man serial' or looked on techpubs.sgi.com? On
    Octane it was programmable to RS232 or RS422, but I believe the cable
    wiring for the two standards is different - i.e. an RS232 cable/device
    may not work properly with the port in RS422 mode, and vice-versa.
    'man serial' shows the difference in pinouts anyway, if you need to
    adjust your cable spec.

    I'm not much of a coder, sorry!
