what does the GDP port acutally do?

Found in Settings, System, External GPS, Programs

I know that it says that this is the port that GPS data communicates with software wanting GPS data but how does that actually differ to COM9 which communicates the GPS Data.

I know it sounds like a strange question, but please read it twice and it will make more sense.

Thanks

This is the MS virtual GPS driver port that interface with the actual physical on-chip GPS port COM9. This basically functions like gpsgate such that multiple GPS app can open that GDP port simultaneously.

thanks ww2250,

that was a very clear explanation. I had heard that these newer handsets could do what Fransons GPS Gate could do!

It does give you the option to set it as a COM port or just nominate a GDP port. How do you know which one to use?

And is it best set to none (aswell as disabling 'manage my connections automatically') if only 1 application needs access to the gps data?

thanks.

If you are just using one app at a time, i.e. no simultaneous opening of any GPS port, these settings shouldn't concern you. It will work regardless of what you set in the GPS applet if you use COM9 directly.

I do plan on running multiple applications at the same time.

Infact,whilst I am running TomTom Navigator 6, I am trying to run in the background a datalogging program, called GpsDIS by E Gerlach.

So whilst 2 apps are needing the NMEA data, what should I set the GDP port to?

(on a related separate note, does WM6 have vb runtime built in, or does it have to be installed?)

thanks

Then you just choose GDP1 as the virtual port and COM9 as the physical port in the GPS applet. In your GPS app, use GDP1.

There are some old stuborn apps that just refuse to use ports other than COMX, however.
