  • Checking that hardware serial pins are working on a Raspberry Pi.
    • Connect a jumper between Pin 8 and 10 creating a loop-back.(Basically we are connecting the serial output pin to the serial input pin)
    • Open a terminal Program like Minicom connecting to serila port /dev/ttyAMA0
    • Test it by typing. All input should be echoed back if it is working correctly.
