Want to create my own program for displaying GPS info

[ESPN Lover]

In my case I have a Dell Axim with a Pharos GPS system. The included
software is Ostia, which doesn't allow me to display altitude, direction,
and speed on the same screen as the map. So I'd like to write my own app to
handle the presentation of the information. How do I get the info from the
GPS?

Which model GPS system are you using? If it plugs into the sync port, you
can open the serial port to read the stream.

http://www.boondog.com/\tutorials\gps\gps.html has a discussion about
decoding the GPS string.

It plugs into the CompactFlash port (I think that's what it is called) at
the top of the PocketPC. Any info on grabbing the stream from the CF port?

It's likely that they have a virtual serial port driver that gets installed
as part of the software install. Based on the software documentation on
their web site, this appears to be the case. Try connecting to the various
COM ports on the device with a terminal emulator. If I remember correctly
the port should be confiured with 4800,N,1.

Once you find the correct COM port, you should be good to go. You will
likely want to provide a way for the user to select the COM port from within
your application.

This folks appear to provide some tools that may help:
