Very good Arnd, if you will supply it I actually am less picky. I even think if I run into severe incompatibility issues between javagps & the mouse output we could simply swap the model...
Essentially I am not going to survey. So the accuracy is not overly important. I'd say I'd need the following: - USB Mouse with drivers which emulate serial interfaces under Windows XP & Linux - with a cable of at least 2 meters, to avoid the need of an extender - it should output NMEA for a start, but I am willing to test Sirf/Garmin as well Thanks for your support..
