==Disable Pi Serial Console==

Simple script to easily enable &amp; disable the Raspberry Pi's serial
console. Disabling the serial console is required if you want to use
the Raspberry Pi's serial port (UART) to talk to other devices e.g.
microcontrollers (see <http://elinux.org/RPi_Serial_Connection> for more
information).
