title: Does RtsEnable or DtrEnable properties send a signal?
body: <p>I want to know if I put these in my code, does computer send any kind of signal to the device?</p>
  
  <pre><code>SerialPort myport = new SerialPort("COM1");
  
  myport.DtrEnable = true;
  myport.RtsEnable = true;
  </code></pre>
  
  <p>I'm required to send a signal on specific pins to the device. As I know Dtr and Rts use pins 4 and 7. So when I write the code above, will my computer send a signal on pins 4 and 7? Or is there a simple way to send a signal on a specific pin?</p>
