Generic Projector Integration via Serial

from my research, a number co projectors use hex commands to operate, if a generic projector component could be made that supports a collection of dictionaries of hex commands per projector model it would br really easy to add new projectors.

I have the serial commands for integrating a Viewsonic projector, but I have been unsuccessful in my attempts to modify the Acer projector component to use them, can anyone help me get the important parts (power on/off, state, input) working on this projector?
Any help (or pointers in the right direction would be wonderful!

Have a look at this post

I have put up a custom component that I use with iTach devices. In theory it might work with your projector commands as short term fix.
