  PURPOSE : This function is called by the interpreter part of the
            ACI in case of the detection of an unknown command.

            <command> : remaining unparsed command string.
            <len>     : length of command string. This value must be
                        incremented by the amount of parsed characters 
                        by this function.
            <output>  : this parameter can be used to display some
                        strings at the AT command interface.
                        The first char of one string must contain
                        the length of the following string. The
                        special length 0xff must be used to define
                        the end of the string list.
