GPS Port Checker

If you're wondering if your old GPS product still works, and you're lucky enough for it to have a USB port that can be connected to a PC, GPS Port Checker could be an app to have by when in a pickle. Why? Because this simple application checks if any particular GPS device connected to the PC successfully sends any data. All you have to do is connect the device to your machine via USB, launch the application, and conduct a scan for devices.

The program is as simplistic as you'd imagine. The only options you have are the GPS Type, which can be Garmin, Magellan, or Other. You'll most likely end up having one of the first two anyways. The app can establish a successful connection to your device once it manages to find NMEA-type data sent by your device through any of the associated COM ports.

This is exactly how it can tell if the GPS is indeed functioning properly or if it's not capable of being used any longer. The Show Com Ports button can also be helpful in identifying the default associated port with your device. The same can be said about the Find GPS button, only that in this particular case the function you launch by clicking the button will start looking for the device itself, not just the port.
