I am interested in this as well.  I have a Optoma HD-80 projector.  It is
used for two purposes, MythTV and Blu Ray. Currently I have a Harmony remote
but for some reason the thing wont turn off.  It always misses the double
push of power from the remote.  So i have to manually click it.

I does have a serial port and I have tried using it before.  Optoma said
could test with just by using hyperterminal to connect to it but I could not
ever get any response.

Does anyone know if USB Serial adapters work with this application?

Ron, do these details look the same as what you used?
