A split cable may be the best way to go about this.

I hooked the D7a w/GPS up to my laptop and ran HyperTerminal.
With the D7a in packet mode I could see packets from the local APRS
network but no GPS sentences.
With the D7a in APRS mode I could not see any data from the D7 at all
in Hyperterminal.

In UI-View there is a file of initialization cmds that get sent to the 
D7a when it is run as a TNC. One of these is: "GPSTEXT $GPRMC".
