I'd originally posted to alt.3d about controlling some LCD shutter
glasses through the serial port on an SGI Personal Iris, and people
suggested that I post here.

Does anyone know how to control the DTR and RTS lines on the Personal
Iris serial port?  Specifically I'm building a controller for some
low-cost LCD shutter glasses for a Silicon Graphics machine, and need
to be able to talk to it over a port.  The serial seemed like the most
likely, but I'd need tighter control over it than 9600bps would
provide.  Besides, I'd rather not be forced into wiring up the
circuitry to deal with serial port I/O right now.

Thanks,

Tom Benedict
