title: Is is possible to simultaneously use Arduino serial monitor while receiving data from Processing?
body: <p>I am attempting to send some data from <a href="http://en.wikipedia.org/wiki/Processing_%28programming_language%29" rel="nofollow">Processing</a> to my Arduino over the serial connection so that the Arduino can control an LED strip. Could I view the serial monitor while this transfer was taking place?</p>
  
  <p>It is irking me that I cannot use any <code>Serial.println</code> statements (for debugging) while Processing is communicating with the Arduino. Everytime I try I get</p>
  
  <blockquote>
    <p>Serial port 'COM3' already in use. Try quitting any programs that may be using it.</p>
  </blockquote>
  
  <p>Is there a way for this serial communication to take place while I view the serial monitor at the same time?</p>
