[App_rpt-users] Dial and APRS support?

[Bob Roszkowski]

I believe that the implementation of APRS in an Allstar node was to
announce the node on the network and its status (Linked to?).   That's what
I have been using it for many years.  This was not designed specifically
for mobile nodes.  APRS is radio-less and has no tie into the repeater/node.
