/**
* @brief This is the underlying stream buffer which implements the
* streambuf class and overloads the overflow() and sync() methods
* @details
* This class is used to modify the output of the stream, for example by adding.
* It also calls the char printing function which is implemented in the
* board supply package (BSP).
