namespace barcode_scanner
{
    public class Program

        public static InputPort bsr = new InputPort(Pins.GPIO_PIN_D0, false, Port.ResistorMode.Disabled);
        public static OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);

        public static void Main()
        {

            SerialPort mySerialPort = new SerialPort("COM1");

            mySerialPort.BaudRate = 9600;
            mySerialPort.Parity = Parity.None;
            mySerialPort.StopBits = StopBits.One;
            mySerialPort.DataBits = 8;
            mySerialPort.Handshake = Handshake.None;

            mySerialPort.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);

        }

        public static void DataReceivedHandler( object sender, SerialDataReceivedEventArgs e)
        {
            led.Write(true);
            Thread.Sleep(1000);
            led.Write(false);
            Thread.Sleep(Timeout.Infinite);
        }

我正在使用上面的代码通过一个通过分线板​​连接到我的netduino plus 2的串行端口(RS232到TTL转换器-

I'm using the above code to receive data through a serial port connected to my netduino plus 2 via a breakout board (RS232 to TTL converter- http://www.embeddedmarket.com/products/RS232-to-TTL-Converter/). The data i want to receive is from a barcode scanner whose output is a RS232 female, so i use a RS232 male to male cable and then use the above mentioned breakout board to connect to netduino plus 2. Upon use of the above code led doesnot blink. All i want to do is blink the led when data is read from barcode scanner i.e., when the barcode scanner scans a barcode. Please help me resolve this. Thanks in advance.
