        private const int BaudRate = 9600;      


        public Form1()
        {
            InitializeComponent();
        }


        private void Form1_Load(object sender, EventArgs e)

            foreach (var portName in portNames)
            {
                comboBox1.Items.Add(portName);

            _serialPort = new SerialPort(comboBox1.Text, BaudRate, Parity.None, 8, StopBits.One);      
            _serialPort.DataReceived += SerialPortOnDataReceived;
            _serialPort.Open();
            textBox1.Text = "Listening on " + comboBox1.Text + "...";

            if (InvokeRequired)    
                BeginInvoke(new Closure(() => { SerialPortOnDataReceived(sender, serialDataReceivedEventArgs); }));     
            else
            {
                while (_serialPort.BytesToRead > 0) //<-- repeats until the In-Buffer is empty
                {
                    textBox1.Text += string.Format("{0:X2} ", _serialPort.ReadByte());
