title: Emulate serial port
body: <p>Is it possible to create a "virtual" serial device that sends data through a "virtual" serial port? I need to develop some code to interact with an Arduino but don't have it with me. Can it be done with <strong>socat</strong>, or some code that writes to a <code>dev/ttyXXX</code> file?</p>
  
  <p>EDIT: I'm running Arch Linux</p>
