  Interrupt:   1Bh
 
  Title:       CTRL+BREAK Handler
 
  See also:    CTRL+C Handler, Keyboard Data Memory
 
  Description:                                          [PC] [AT] [PS/2]
 
     Invoked by Int 09h (keyboard) when it detects CTRL and BREAK keys
     pressed simultaneously. Usually terminates current process.
 
     To trap Int 1Bh calls, a program must set up a handler routine to
     gain control when the interrupt occurs. TSR programs that accept
     keyboard input should trap Int 1Bh calls with a handler to prevent
     the existing handler from responding to the keypress.
