+  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.
