When the 710 is in APRS mode you can get all the data from the TNC on 
this PS2 connector as long as you enable menu 604 "COM PORT OUTPUT: ON"

And yes it's possible to send messages from the 710 via the same 
connector even when the radio is in APRS mode.

I have made a program doing this. The 710 is working in APRS mode and i 
can choose to enter messages via the radio or from my program.

i'm just fishing here ;o) but i take it that this is possible so maybe 
maybe after all other projects you have :o)
