On an IRIX system just type in: man serial.

     The DIN-8 serial port connectors on the Indigo, Indy, Indigo2, Challenge
     S, Challenge M, Power Challenge M, and the MENET 4-Enet, 6-serial board
     (XT-FE-4TX-6A) have the following pin assignments.

                                     ---------
                                    / 8  7  6 \
                                   (  5  4  3  )
                                    \  2   1  /
                                     ---------

Under IRIX you can use both assignments - you choose it by the devicename
you are talking to.
