Embedded software serial communications protocol

This is a way to have my various arduino-nano controlled embedded perhipherals talk to each other, and to the Raspberry pi using any 3 available GPIO ports. Sometimes I need more than one perhipheral to talk to a controller, and I run out of dedicated serial ports. This allows the use of any 3 GPIO pins on the controller and perhipheral to facilitate two-way non-blocking communications.
