we have an free (with source) system that allows you to use the serial
ports on a linux box (cheap PC) with Performer (or other libs) on an IRIX
box.... it also allows for multiple application access to the serial port.

saving you the grief of using a million dollar box for serial comm!

if you are interested, email me.
