This program runs on an atmega (Arduino Mega 2560 in this case) to create a sort of dummy terminal/teletype using a ps2 keyboard and parallel dot matrix printer and interfacing with it over the Arduino's main builtin 5V TTL serial interface.

Notes: Pin 14 on an Arduino Mega is labelled D14, However on boards where there are only 13 digital pins, it is labelled A0. The DEBUG flag also only works on this Arduino as it has extra serial interfaces
