Notes

this function does not use any of the DOS-internal stacks and may thus
        be called at any time; one possible use is modifying Control-Break
        checking from within an interrupt handler or TSR
      not supported by DR DOS through version 6.0 (error code 01h);
        newly-supported by Novell DOS 7
