title: Windows command line com-port writing for Arduino
body: <p>I need to send some information from my PC to an Arduino. I tested it with <a href="http://en.wikipedia.org/wiki/PuTTY" rel="nofollow">PuTTY</a> and it works great.</p>
  
  <p>I need to send characters, '1' or '2', to control a servo and I am  using these commands: </p>
  
  <blockquote>
    <p>mode com10:9600,n,8,1</p>
  </blockquote>
  
  <p>... and I see that my Arduino received some data.</p>
  
  <p>After that, I try to use that:</p>
  
  <blockquote>
    <p>echo 1>com10</p>
  </blockquote>
  
  <p>OR</p>
  
  <blockquote>
    <p>echo "1">com10</p>
  </blockquote>
  
  <p>and nothing nothing happens.</p>
  
  <p>With PuTTY it works corrent and turning, when I press 1 or 2. With the Arduino serial monitor it works great too.</p>
