title: pySerial program doesn't read serial correctly
body: <p>I have a problem using pySerial, and I don´t know from where to start looking for.
  I have a 64 bits Windows Seven OS, with Python 2.7.5 (32 bits), and pySerial and Arduino (Arduino working correctly) already installed.</p>
  
  <p>My Arduino code is the following: </p>
  
  <pre><code>// the setup routine runs once when you press reset:
  void setup() {                
    // initialize the serial in 19200 baud rate
    Serial.begin(19200);     
  }
  
  // the loop routine runs over and over again forever:
  void loop() {
    delay(1000);               // wait for a second
    Serial.print("hello");
  }
  </code></pre>
  
  <p>(Arduino conected in COM8, when using Serial Monitor I can see it saluting)</p>
  
  <p>And my PySerial code looks like this:</p>
  
  <pre><code>import serial
  import time
  
  arduino = serial.Serial("COM8", 19200)
  time.sleep(2)  
  
  while True:
      print arduino.readline()
  </code></pre>
  
  <p>When I start this script, the program runs, but I can´t see the serial output (I think the configuration in the Python script is OK because if something - e.g. the port - is wrong, it crashes).</p>
  
  <p>I don´t know what to do to find a solution.
  Can you help me?</p>
