title: Reading data from NodeJs Serialport
body: <p>I would like to be able to read data received by the ascii command sent.</p>
  
  <p>Below is the code that sends command to my lock controller</p>
  
  <pre><code>var express = require('express');
  var router = express.Router();
  var SerialPort = require('serialport');
  
  
  /* GET home page */
  router.get('/', function(request, response){
  
  
      SerialPort.list(function (err, ports) {
        ports.forEach(function(port) {
          console.log(port.comName);
          console.log(port.pnpId);
          console.log(port.manufacturer);
        });
      });
  
  
      var port = new SerialPort("COM5", {
    baudRate: 38400
  });
  
      port.on('open', function() {
          // NodeJS v4 and earlier
          port.write(new Buffer('status1', 'ascii'), function(err) {
            if (err) {
              return console.log('Error on write: ', err.message);
            }
            console.log('message written');
  
          });
      });
  
      // open errors will be emitted as an error event 
      port.on('error', function(err) {
        console.log('Error: ', err.message);
      });
  
  });
  
  // Important
  module.exports = router;
  </code></pre>
  
  <p>In the doc, it mentions the use of parsers to try and read data, <a href="https://github.com/EmergingTechnologyAdvisors/node-serialport#serialportparsers--object" rel="nofollow">https://github.com/EmergingTechnologyAdvisors/node-serialport#serialportparsers--object</a> but I am not sure how to implement it, and I would want to execute after the command <code>status1</code> has been written.</p>
  
  <p>Essentially logs the response of the command succesfully written to the console</p>
