It's the Foxboro name for the gateway: GP = Gateway Processor. I believe ours
are GP30's... upgraded from GP10's a couple of years ago....

Subject: RE: AB KF2 at 19.2 Kbaud?
Very interesting Kirk, we also are using KF2 modules at 9600 baud, but with
a small twist. We are connecting to a SLC504 via a radio modem. By the
way, this may be a stupid question, but what is a GP?
Regards
John Campbell
