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.
