*
* Super trivial example exercising the UART serial communications line.
*
* It's purpose is to show how SimulAVR can redirect serial communications
* in a way useful for running in a simulator, while requiring NO code
* modifications which would change it's behaviour compared to running
* on real hardware or disallowing to run the very same compiled binary
* on that hardware. The compiled binary should work in the simulator just
* as fine as on hardware.
