I am having difficulty acquiring GPS data from the Blackjack II using the
gpsapi.dll. It works fine on the emulators and with FakeGPS, but still no
luck with the actual phone.

I am able to open the device without receiving an exception:
[DllImport("gpsapi.dll")]
       static extern IntPtr GPSOpenDevice(IntPtr hNewLocationData, IntPtr
hDeviceStateChange, string szDeviceName, int dwFlags);

I know of the MoCaDo hack but I do not want to have to use it to send the
data to COM4.

Any ideas?
