Follow this guide to have your virtual port displayed in the device manager:
Here's where it gets weird. Both Streets and Trips and Street Atlas recognize all of the virtual com ports created by GPSGate. BUT, while both FlightMap and FlightDeck reported seeing all the ports, neither one could open 10, 11 or 12 yet both worked perfectly with COM1 and COM2!!!!!
This is a limitation in Street Atlas and S&T, they cannot handle a port number greater than COM9, that is a bug in those application and has nothing to do with GpsGate.
Use a lower port number for them. You can also report those errors to the technical support of respective product.
If you find applications that does not work with GpsGate as you expect, it is always good to report it to us, and post it in this forum. It is also recommended that you contact the support of the product in question and inform them that the product does not work properly with GpsGate. We will help them to work out the technical details.
Finally, although GPSGate gives you a remove button for output ports, it does not provide any way of cleaning up input ports. Is there any way to do that?
This is just a history list, so you fast can set an old input back. To delete history you can remove the folder "c:\program files\franson\gpsgate 2.0\HistoryInput". But it will do no harm to keep it. There is currently no way top disable the history feature.
