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.
