I cannot create virtual port using GpsGate for Windows XP/2k/NT
This is fixed in GpsGate 2.0 and later
"3: Failed to create virtual serial port"
The installation of the driver failed during GpsGate installation. This sometimes happens on some systems, (for yet unknown reasons). To reslove this follow those steps:
1. Download http://franson.com/gpsgate/GpsGateCtrl.zip
2. Unzip the file.
3. Run GpsGateCtrl.exe
4. Click "Install Driver"
5. Now you can create virtual ports
Another reason might be that you have a GpsGate Express license. In those cases you can only create 2 virtual ports.
