Well, AX.25 is the link layer protocol used on packet radio.  In the overall
scheme of things, it's roughly analogous to Ethernet on the LAN or PPP on
dialup.  AX.25 does have some rudimentary network layer facilities, namely
digipeater routing.

But in a real network scenario, one would (and I did 30 years ago) run IP over
AX.25 UI frames.  You can even include a digipeater in the path, if needed,
though where possible, it's best not to have a digipeater at the AX.25 layer
and let IP do the routing.

I'm thinking of doing the same here.  I have to hook up a radio to the packet
system, which means making up a db9 to 6 pin adapter, then buying a Signalink
cable for the Yaesu.  Doing it this way means I only need the one oddball
cable, regardless of what radio I use.  I use the 6 pin mini DIN (1200 bps)
connections as my standard packet connector format.  I hate working on those
mini DIN connectors too, might consider cheating there as well.

Tell me about it!
