Command: break

  BREAK sets extended CTRL+C (STRG+C) / Control-Break checking to on
  [default] or off. When set to on, the kernel will perform the check 
  (and invoke current handler if pressed) prior to most int 21h calls.
  When set to off, the kernel only performs the check on I/O calls using
  standard streams.
  BREAK can be used in CONFIG.SYS / FDCONFIG.SYS (see also here) 
  and while running FreeDOS.

Syntax:

  BREAK [ON | OFF] [/?]

Options:

  ON   CTRL+C (STRG+C) is even tested while an access 
       to diskette or HD
  OFF  CTRL+C (STRG+C) is only tested if there is an
       output on the screen. Default=OFF
  /?   Shows the help

Comments:

  Type "BREAK" without a parameter to display the current BREAK setting.
  If BREAK is ON, programs and commands can always be aborted by typing 
  CTRL+C (STRG+C).
  If BREAK is OFF, programs and commands can only be aborted if you get
  an output on the screen.
  BREAK can be used in CONFIG.SYS / FDCONFIG.SYS (see also here)
  and while running FreeDOS.
  BREAK is a command internal to kernel.sys and needs no other file
  in order to work.

Examples:

  IN CONFIG.SYS / FDCONFIG.SYS / COMMAND LINE:
    break on   programs can be aborted by CTRL+C (STRG+C)
    break off  programs cannot be aborted by CTRL+C (STRG+C)
