It goes even deaper that that...

First, the new SGI machines have the standard PC rs-232 pinouts. This
is different from the Onyx and older machines.

Second, with the help of ascension, the Iowa State guys got their
ascenion tracker up and running with the following relevations:
        1) calling a serial port by the name ttyd# does not function
                the same way on Onyx vs Onyx.
        2) Use ttym# instead
        3) Use a straight through cable (not NULL modem)
        4) Make sure that only pins 2, 3, and 5 are connected

My guess (hope) is that similar things will hold true for the Polhemus
systems as well.
