20.2 Break
==========
-- Command: break [duration]
('C-a b', 'C-a C-b')
Send a break signal for DURATION*0.25 seconds to this window. For
non-Posix systems the time interval is rounded up to full seconds.
Most useful if a character device is attached to the window rather
than a shell process (⇒Window Types). The maximum duration
of a break signal is limited to 15 seconds.
-- Command: pow_break
('C-a B')
Reopen the window's terminal line and send a break condition.
-- Command: breaktype [tcsendbreak|TIOCSBRK|TCSBRK]
(none)
Choose one of the available methods of generating a break signal
for terminal devices. This command should affect the current
window only. But it still behaves identical to 'defbreaktype'.
This will be changed in the future. Calling 'breaktype' with no
parameter displays the break setting for the current window.
-- Command: defbreaktype [tcsendbreak|TIOCSBRK|TCSBRK]
(none)
Choose one of the available methods of generating a break signal
for terminal devices opened afterwards. The preferred methods are
'tcsendbreak' and 'TIOCSBRK'. The third, 'TCSBRK', blocks the
complete 'screen' session for the duration of the break, but it may
be the only way to generate long breaks. 'tcsendbreak' and
'TIOCSBRK' may or may not produce long breaks with spikes (e.g. 4
per second). This is not only system dependent, this also differs
between serial board drivers. Calling 'defbreaktype' with no
parameter displays the current setting.
