The Yaesu APRS radios have (in my opinion) a fatal design flaw/oversight.   The 
serial port is only for configuring the radios settings and memories. You do 
not have access to the TNC data stream the way you do in the Kenwood 
radios.     The only APRS/packet operation you can do with the Yaesus is from 
the radio's front panel.
