+ *
+ * Purpose: The parameter serial_info allows knowing all serial information
+ *          necessary to set up the serial configuration of an application.
+ *          From this information, the function is able to determine if the
+ *          current serial configuration read out from the flash memory is
+ *          valid. If it does not correspond to an allowed configuration, the
+ *          default configuration is selected. This function must be called at
+ *          the application's initialization, but never after.
+ *
+ * Parameters: In : serial_info: application serial information like the default
+ *                               configuration and all allowed configurations.
+ *             Out: none
