> 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.

Possibly a dumb question, but were you using a straight or null-modem
cable? The Sharps require null-modem (owners of other models feel free
to correct me), as does your Optoma (pins 2 & 3 crossed, 5 straight is
all you'd need).
