title: Serial communication with Raspberry pi
body: <p>How can we do serial communication using the raspberry pi with a python script to send/receive data to my laptop? If yes can we use the RS232 cable to connect to the TX/RX ports on the raspberry pi directly? If yes, what pins must be used from the RS232 cable? It would be help full if anyone can post a example python script?</p>
  
  <p>Since my first aim is to send/receive data to the laptop to/from the raspberry pi, i'm using a   RS232 to USB cable at both end to connect to the laptop as well as the raspberry pi.</p>
