Int 15 Fn 12  - Topview - Send Message - "addto" - Set Object Bits         [Q]

   AH = 12h
   BH = 0Ah
   BL = object
       00h handle is DWORD on top of stack
       timer: start timer for specified interval
       pointer: set control flags
       keyboard: set control flags
       04h set control flags on KEYBOARD object (handle on top of stack)
       05h set control flags on task's default KEYBOARD object
   STACK: (if timer)   DWORD duration in 1/100 seconds
          (otherwise)  DWORD bits to set

For keyboard objects, the bits have the following significance:
   bit 15 reserved, can't be set
   bit 14 unused
   bit 13 reserved, can't be set
   bit 12-6 unused
   bit 5  (DV 2.2+) exclusive input
   bit 4  filter all keys (used with handler established by SETESC)
       if 0, only keys that would normally be displayed are filtered
   bit 3  program continues executing while input in progress
   bit 2  insert mode active for field mode
   bit 1  hardware cursor displayed when task is hardware cursor owner
       must be set if keyboard in field mode and field table includes
       input fields
   bit 0  keyboard is in field mode rather than keystroke mode

For pointer objects, the bits have the following significance:
   bit 15 reserved, can't be set
   bit 14-8 unused
   bit 7  mouse pointer is hidden while in window
   bit 6  get messages even if window not topmost
   bit 5  get messages even if window not foreground
   bit 4  multiple clicks separated by less than 1/3 second are counted
       and returned in a single message
   bit 3  pointer position is relative to screen origin, not window origin
   bit 2  send message on button release as well as button press
   bit 1  (DV 2.23+) send message with row=FFFFh and col=FFFFh whenever
       pointer leaves the window
   bit 0  send message only on button activity, not movement
          DV-specific, and INT 15/AX=DE0Fh must have been called first
