I have a Delorme Earthmate GPS receiver and I'm having trouble getting it to work on my empeg with gpsapp. I've added the protocol=earthmate line under [gpsapp] to the config.ini file. It just sits at the "waiting for signal" screen forever. I bought a male to male straight thru cable from radio shack along with a null modem adapter (which i believe makes it crossover?) I am also unable to get my laptop connected by serial in car with hyperterminal (after forcing AC mode with hijack)

On AC power I can connect my laptop via hyperterminal without any problems. I tried getting the gps receiver working on AC power by forcing DC Mode with hijack but it doesn't work that way either. The gps receiver works fine with my laptop just doesn't seem to want to work with the empeg. Does anyone know what I could be doing wrong or have any suggestions?
