The application cannot see Virtual COM Ports GpsGate has created
You can create Virtual COM Ports in GpsGate, but you cannot see these ports in your GPS application.
CAUSE / SOLUTION
GpsGate publishes the Virtual COM Ports in the registry under HKEY_LOCAL_MACHINE\Hardware\DeviceMap\SerialComm. To be compatible with GpsGate, the application needs to look there to find the COM ports.
Applications that only look in the Device Manager for COM ports will not find the Virtual COM Ports created by GpsGate.
