title: Ruby EventMachine serial connection to arduino?
body: <p>I have a Ruby application that connects to a serial device via USB(an Arduino, non-firmata kind).</p>
  
  <p>I am exploring the possiblity of using EventMachine for non-blocking bidirectional I/O but can not find any examples. <strong>Does EvenMachine support serial connections?</strong> We're currently using our own nonblocking IO framework and I would prefer to not reinvent the wheel.</p>
  
  <p>Currently, all control is done through a Serial object via the serialport gem. I believe it is a subclass of the IO Class in Ruby.</p>
