title: Write then wait for response serialport nodejs
body: <p>i'm trying to use serialport.js and I wondered how can it be possible to write and wait response from the other side because all is asynchronous. </p>
  
  <p>My problem is I must know to which response is associated the send message.</p>
  
  <p>I think that involve to manage when response never send from the other part.</p>
  
  <p>Should I use queue system ? is there a example to do it or a library ?  </p>
  
  <p>thanks in advance.</p>
