If you are reading the data from a serial port: private void comPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { if (!this.Open) return; // We can't receive data if the port has already been closed. This prevents IO Errors from being half way through receiving data when the port is closed. string line = String.empty; try { line = _SerialPort.ReadLine(); line = line.Trim(); //process your data if it is "DATA C", otherwise ignore } catch (IOException ex) { //process any errors } } reference: http://stackoverflow.com/questions/11571522/clear-serial-port-receive-buffer-in-c-sharp Mark This Response as Answer -- Chandu http://www.dotnetfunda.com/images/dnfmvp.gif Sudhakar_A, if this helps please login to Mark As Answer. \| Alert Moderator

If you are using the System.IO.Ports.SerialPort then you could use the two methods:

DiscardInBuffer() and DiscardOutBuffer() to flush the buffers.

If you are reading the data from a serial port:

private void comPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
    if (!this.Open) return; // We can't receive data if the port has already been closed.  This prevents IO Errors from being half way through receiving data when the port is closed.
    string line = String.empty;
    try
    {
        line = _SerialPort.ReadLine();
        line = line.Trim();
       //process your data if it is "DATA C", otherwise ignore
    }
    catch (IOException ex)
    {
        //process any errors
    }
}
