pub fn tcsendbreak(fd: RawFd, duration: c_int) -> Result<()>
Transmits data to generate a break condition.
If the terminal device is using asynchronous data transmission,
tcsendbreak() transmits a
continuous stream of zero bits for a specific duration.
fdshould be an open file descriptor associated with a terminal.
durationcontrols the duration of the transmitted zero bits. A value of 0 causes a transmission between 0.25 and 0.5 seconds. A value other than 0 causes a transmission for an implementation-defined period of time.
