(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 (see Window Types). The maximum duration of a break signal is limited to 15 seconds.
Reopen the window’s terminal line and send a break condition.
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

TIOCSBRK. The third,
TCSBRK, blocks the complete
session for the duration of the break, but it may be the only way to
generate long breaks.
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.
defbreaktype with no parameter displays the current setting.
