Saves the mouse driver state in a user buffer. The minimum size for the buffer must be determined by a previous call to Int 33H Function 15H.
Call with:
AX = 0016H
ES:DX = segment:offset of buffer
Returns:
Nothing
Note:
Call this function before executing a child program with Int 21H Function 4BH (EXEC), in case the child also uses the mouse. After the EXEC call, restore the previous mouse driver state with Int 33H Function 17H.
