Seems easy enough. Use perl and the server port. If your perl script
detects DHCP is now up, then it could send a basic APRS message to the
server port saying something like "Turn Interface 0 ON" or "Turn
Interface 0 OFF", scince APRS data sent to the server port is never
gated, then only your box would see it, and you would get a message
notice telling you that information. The parser would only start
interface 0 if the sender matched an internal ID code, like Callsign-PL
or whatever.
