title: What character represent "Enter" for serial communication?
body: <p>I am trying to send a serial command using my Arduino, but I can't find out how to replicate the <code>Enter</code> key.  I've tried <code>\r\n</code> as well as <code>\n</code> and neither of those seem to do it.</p>
  
  <p>I've tried the Arduino functions <code>Serial.write()</code> <code>Serial.print()</code> <code>Serial.println()</code> and none of those work either.</p>
  
  <p>What can I use to replicate the <code>Enter</code> key?</p>
  
  <p>Thank you</p>
