title: node serialport not displaying serialport data in raspberryPI
body: <p>I am trying to read the serialport data coming from Arduino to Raspberry PI but it doesn't display anything. I have verified that the data is arriving in the serialport. The same script works fine in windows 7. Also I have tried two different approaches of reading the serial data but none of them work.
  The node.js version I am using is v0.9.9.</p>
  
  <p>Any help will be greatly appreciated.</p>
  
  <pre><code>var sys = require('sys');
  var portName = '/dev/ttyACM0' ;
  
  /////////////////////////////////////////////////
  //Approach 1
  /////////////////////////////////////////////////
  var SerialPort = require("serialport").SerialPort
  var serialPort = new SerialPort(portName, {
       baudrate: 9600
     });
  
  serialPort.on("open", function () {
  console.log('open');
  serialPort.on('data', function(data) {
  //console.log('data received: ' + data);
  sys.puts("here: "+data);
  });
  
  serialPort.on('error', function(message) {
  console.log('error: ' + message);
  });
  });
  
  /////////////////////////////////////////////////
  //Approach 2 
  /////////////////////////////////////////////////
  var serialport = require("serialport");
  var SerialPort = serialport.SerialPort; // localize object constructor
  
  var sp = new SerialPort(portName, { 
       parser: serialport.parsers.raw
       });
  
  sp.on("data", function (data) {
  sys.puts("here: "+data);
  });
