title: Disable serial console of raspberry pi
body: <p>I follow the guide in this site <a href="http://elinux.org/RPi_Serial_Connection" rel="nofollow">http://elinux.org/RPi_Serial_Connection</a> to disable linux from using serial port, but it's clearly that this will also prevent me from log in to Raspberry Pi by using Minicom. How can I access Raspberry Pi via Minicom to work? 
  I am trying to transmit data from RaspberryPi to Linux PC but it doesn't work. I thought disable serial port is a solution but it causes another problem for me to log in and run script. 
  Help me please???</p>
