When this application is run on the Windows 10 Desktop PC it functions as intended.

When ran from the Raspberry Pi, the application functions as intended, except for when the target RS-232 device has it's RTS line low (or serial cable unplugged). At that point the IOT OS will hang and eventually go to a blue screen with a watchdog fault.

It is intended to examine the value returned by the .StoreAsync() method following it's execution or timeout based on the .WriteTimeout parameter.

                Task<UInt32> storeAsyncTask;
                storeAsyncTask = PortDataWriter.StoreAsync().AsTask();    //<----This is where it hangs in IOT Core
                uint x = await storeAsyncTask;

This works properly in the Windows Desktop environment, but the line above is what appears to cause the Windows IOT Core environment to hang.
