Hi Brian I wrote two applications (GPSacreage and ThatWay!) the interfaces to NMEA GPS devices like you want to do. In my case I found the problem was not so much catering for different GPS types, but rather different PalmOS versions. You have to make sure that you open and close the serial port using the correct method (old or new serial manager). I first check that which OS version and then depending on this open the serial port in the correct manner.
This seems to work with almost all NMEA GPS devices except one... the Navman 500. In the case of the NavMan I recieved NMEA data, but the GPS itself just never gets a proper satelite fix. I'm not sure if it is because the GPS expects some initialisation string or something. I have written to its manufacturers and posted questions to forums, but so far no answer to this riddle. If you find the answer to this I would also be very interested. Please feel free to write to me personally at [EMAIL PROTECTED] if you need more assistance.
