        help
            Linenoise line editing library provides functions to save and load
            command history. If this option is enabled, initializes a FAT filesystem
            and uses it to store command history.

    config CONSOLE_IGNORE_EMPTY_LINES
        bool "Ignore empty lines inserted into the console"
        default y
        help
            If an empty line is inserted to the console, the Console can either
            ignore empty lines (the example would continue), or break on empty lines
            (the example would stop after an empty line).
