[aprssig] IGATE beacon format?

[Chris Kantarjiev]

I think that javAPRS initiated the practice of regularly sending a beacon 
tha begins "<IGATE" with some status after it. This appears to be another
one of those undocumented "APRS standard practices"; the documentation 
indicates how to configure the status beacon, but doesn't indicate what
get sent.

I'd like to teach aprs4r to similar beacons, since I know there are people
mining the ARPS-IS for them to try to map out igate locations. Would someone
please provide the details (and perhaps put them somewhere that a google
search will find them)?

Thanks!
