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 (see Window Types). The maximum duration of a break signal is limited to 15 seconds.
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
breaktypewith no parameter displays the break setting for the current window.
Choose one of the available methods of generating a break signal for terminal devices opened afterwards. The preferred methods are
TIOCSBRK. The third,
TCSBRK, blocks the complete
screensession for the duration of the break, but it may be the only way to generate long breaks.
TIOCSBRKmay 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
defbreaktypewith no parameter displays the current setting.
