Thank you Mr. MacGyver! I will call them first thing in the morning!!!

I'm impressed - you must have one helluva memory. Crap, I can't remember what I had for breakfast, let alone WHERE I BOUGHT something a few YEARS ago - LOL.

As for the interface, that's sounds fairly straightforward. I don't physiclly have the unit with me (I am presently on a contract in Lansing, MI. - and Gawd, do I miss TEXAS!, "Home Sweet Hole-In-The-Ground"), but I think I have a Melco intercom in the KSU, and was thinking that if I could get a handset out to the front gate (900 feet), I could have visitors to the base pick up the phone and ring the intercom line, then I could enter a DTMF sequence from the set I am using to talk to them, having the Melco decode it and trip a relay to open the gate for them.

Hmmmmmm......pondering, pondering, pondering, Zzzzzzz, Zzzzzz, Zzzzzzz.

Thanks for your advice and assistance (adding names to my Christmas Card list).
