I'm surprised I didn't catch the lack of RS-232 support sooner. It's not a show stopper but I'm a little disappointed since the 990 had it, and it would have been nice for control via my home automation system (Homeseer). Given an estimated price for the 978 in the 1K range, one would think RS-232 would be included.

Having said this, I can't fault Outlaw too much for its omission, as few people own HA systems to leverage the interface.
