Great that you got as far as you did....

I for one am absolutely interested....I do custom installs, integrated with home automation.

RS232 control and RS232 feedback would be invaluable for MANY installations, and IMO, for many users once they realize how much flexibility it adds to the 990.

I am anxiously awaiting further clarification on a code control list that is indeed usable, as well as any feedback sent by the 990.

Keep up the superb efforts!!!
