There are various interface programs that can connect to an AX.25 port
and present some other interface acceptable to a program. Additionally
there are ways of tunneling the AX.25 port across a network (such as
AXIP and AXUDP for direct tunneling but you could also potentially use
ssh). There are other ways, too. For a while I was using a setup where
the TNC was on one machine and Xastir was on another. With the program
"socat" I provided access to the TNC across a network.
As far as data present on the various ports the AX.25 port does not
present as an APRS-IS feed. It looks more like a KISS TNC but with some
Xastir's server port is something close to a "cooked" data stream.
Whatever comes from the TNC gets parsed, cleaned up, and then shipped
out the server port. So it looks like a TNC in converse mode. Anything
sent into the server port is echoed right back to the TNC unaltered
which means the data sent must be completely structured as a valid APRS
packet for anything to work.
