title: C# - Example for Handshaking with SerialPort class
body: <p>I'm currently working on a project which requires me to communicate with an MBED through serial ports. </p>
  
  <p>I've read the msdn site but I don't understand.</p>
  
  <p>Can anyone teach me or show examples of how to use <code>SerialPort.Handshake</code> (<code>XonXoff</code> or <code>RequestToSend</code>)?</p>
  
  <p>My main request how to set: If C# reads a certain string, then send data.</p>
