+
−
+
−            <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.
