screen: Power Detach

 
 8.2 Power Detach
 ================
 
  -- Command: pow_detach
      ('C-a D D')
      Mainly the same as 'detach', but also sends a HANGUP signal to the
      parent process of 'screen'.
      _Caution_: This will result in a logout if 'screen' was started
      from your login-shell.
 
  -- Command: pow_detach_msg [message]
      (none)
      The MESSAGE specified here is output whenever a power detach is
      performed.  It may be used as a replacement for a logout message or
      to reset baud rate, etc.  Without a parameter, the current message
      is shown.
