The old ports have been removed, leaving now only 3 to connect to and 1 HTTP port
1314: Message-only Feed
10152: Full APRS-IS Feed (limited to within 300Km of my location)
14580: User-defined Filtered Feed
14501: HTTP status page (this is the only port viewable with a web browser!)
you can telnet into the first 3 however the information you receive back won't make much sense unless you are using an APRS compatible application to interpret the data!
