Command 48 can also be used to clear the “More Status Available”. When the device receives command 48 it

compares the Request Data Bytes to the current value; if there is an exact match it clears the “More Status Available

bit corresponding to the requesting device (Primary Master, Secondary Master, Gateway, etc.). If there is not an exact

match or too few bytes are received then the More Status Available bit remains unchanged. Extra Bytes beyond those

supported by the device are ignored.
