If you are trying to establish comms between 2 boards directly over a wire, I found that I2C/TWI worked better than serial rx/tx (the latter was unreliable and had garbage depending on which board you talk to and many other conditions and noise). You can use a standard Arduino's Wire library and examples for I2C (TWI, two-wire interface is just a different name due to trademarks): https://www.arduino.cc/en/Tutorial/LibraryExamples#wire
