InitializeComponent();

// can be sent through the constructor of the SerialPort class
// PortName = "COM1", Baud Rate = 19200, Parity = None,
// Data Bits = 8, Stop Bits = One, Handshake = None
_serialPort = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);
//_serialPort.Handshake = Handshake.None;
_serialPort.DataReceived += new SerialDataReceivedEventHandler(sp_DataReceived);
_serialPort.ReadTimeout = 2000;
_serialPort.WriteTimeout = 500;
_serialPort.Open();
}
void sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
Thread.Sleep(500);
string data = _serialPort.ReadLine();
this.BeginInvoke(new SetTextDeleg(si_DataReceived), new object[] { data });
}
private void si_DataReceived(string data)
{
textBox1.Text = data.Trim();
