Hello Gary!
"What prevents these other applications from simply reading the GPS data directly?"
I have written an application, that takes the GPS-data from a server. Now, my application creates a NMEA-protokoll with these GPS-data. After that, I want to show these GPS-data in every navigation software (like TomTom for example), which is able to read NMEA-strings. (Both applications runs on one Pocket-PC)
I have tested two null modem emulators. The first is "VSPD Mobile", it runs fine, but it is to expensive. The second is "ComPipe", but i'm not able to run it, there is no data-transfer between the existing com-ports.
Taxmania says, that i have to connect the TX and RX lines of the COM port together and anything will be received from the same port. I think, it's like a cross-over cable, but how should i make this in my Pocket-PC?
Is there no way to program the TX and RX lines in the COM ports?
