[aprssig] Having trouble with APRS setup

I've been trying to set up my APRS equipment and make sure everything
works before I put it in the car. The problem I have is that the TNC
will not key up the radio in GPS mode.
I have the following hardware:
Garmin GPS V Deluxe
Kantronics KPC 3+
Kenwood TH-79A dual band HT
The GPS is working fine because I connected it to my pc and could see
the data displayed in hyperterminal every 2 seconds. The cable that came
with the GPS has a 9-pin female connector, and the TNC has a 25-pin
female connector. I used a 25-pin male to 9-pin female adapter, and a
9-pin male to male gender changer to get the GPS and TNC connected.
I configured the TNC exactly the same as the example shown in the manual
for GPS use. The baud rate is set to 4800 for both the GPS and TNC. The
GPS is set to output NMEA type data. The TNC's receive light comes on as
it normally would when a signal is heard. The TNC will key up the radio
in TERMINAL mode, but not in GPS mode. I used the following parameters
to set up my TNC:
GPSHEAD 1 $GPGGA
LTP 1 GPS via DIGI
BLT 1 EVERY 00:01:00
Does anyone have any suggestions on how to get this going?
