+ * The concerned functions are serial_write() and serial_flush().
+ * These functions should call the scheduler at some point to avoid using more
+ * time than required or even hang the system.
+ * Also note that when an uart receives a character this driver will call the
+ * handler registered by the application (if any). This handler should be kept
+ * as short as possible, and must not call any OS related function as it will
+ * be executed within interrupt context.
