If you haven't already done so, I suggest that you post in the Uniden forum on RadioReference.com. The Uniden product manager is a regular there and may be able/willing to provide more info than whoever got your email at Uniden.
In the meanwhile, I'd respectfully suggest that you lighten up a bit before posting there.
BTW, I'm a lawyer. I don't recall anything in the Constitution guaranteeing a right to rs232 command syntax, but I'll check my sources again just in case.
