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 }}
