stty, gtty — set and get terminal state (defunct)
stty(int fd, struct sgttyb *buf);

The stty() function sets the state of the terminal associated with fd.
The gtty() function retrieves the state of the terminal associated with
fd. To set the state of a terminal the call must have write permission.
The stty() call is actually ‘ioctl(fd, TIOCSETP, buf)’, while the gtty()
call is ‘ioctl(fd, TIOCGETP, buf)’. See ioctl(2) and tty(4) for an
If the call is successful 0 is returned, otherwise -1 is returned and the
global variable errno contains the reason for the failure.
