The Kenwood D700 mobile and TH-D7 handheld both haveTWO serial ports; 
one for the computer and one for the GPS.  On the D700 the main port is 
a DB9 and the gps port is a 2.5mm jack.  On the TH-D7, both ports are 
2.5MM (probably because of the limited panel space on the handheld 
compared to the mobile).   Further both are stereo (to implement a basic 
TXD/RXD/COMMON non-handshaking 3-wire serial port hookup).


[ The TH-D7 speaker/mic jacks are the traditional pair of one 2.5MM jack 
and one 3.5MM. ]
