hi in the raspberry pi Raspbian some time will write problem

"stackTrace": " at RJCP.IO.Ports.SerialPortStream.WriteCheckDeviceError() \n at RJCP.IO.Ports.SerialPortStream.WriteCheck(Byte[] buffer, Int32 offset, Int32 count) \n at RJCP.IO.Ports.SerialPortStream.Write(Byte[] buffer, Int32 offset, Int32 count) in this time i must create SerialPortStream port again i create the serial port once and not close the port until app close

For some reason the main thread died (a critical error). The system won't recover in this case. See the code here:

        private void WriteCheckDeviceError()
        {
            if (m_Buffer != null) {
                if (IsOpen && !m_NativeSerial.IsRunning) {
                    throw new System.IO.IOException("Device Error");
                }
            }
        }

You should enable tracing and look what was reported why the thread died. See the Wiki: https://github.com/jcurl/SerialPortStream/wiki/Tracing

Didn't get further feedback so closing issue.
