Device Error

Trying to read output from Arduino Uno clone (with CH340 on board):

var arduino = new SerialPortStream("COM6", 9600, 8, Parity.None, StopBits.One);
arduino.DtrEnable = true;

arduino.Open();

while (true)
{
    Console.Write(arduino.ReadExisting());
    System.Threading.Thread.Sleep(1000);
}

ReadExisting() throws:

Unhandled Exception: System.IO.IOException: Device Error
   at RJCP.IO.Ports.SerialPortStream.ReadCheckDeviceError(Boolean immediate) in c:\Users\jcurl\Documents\Programming\HELIOS\serialportstream\code\SerialPortStream.cs:line 629
   at RJCP.IO.Ports.SerialPortStream.ReadExisting() in c:\Users\jcurl\Documents\Programming\HELIOS\serialportstream\code\SerialPortStream.cs:line 931
   at ArduinoReader.Program.Main(String[] args) in C:\Users\Andrei\documents\visual studio 2017\Projects\ArduinoReader\ArduinoReader\Program.cs:line 17

Same code with System.IO.Ports.SerialPort works fine.

I’ve made a commit to the branch “feature/dotnet-98” if you could please test. It’s slightly different. If it’s OK, I’ll merge and put in the next release.
