Struct termios::Termios
[−]
[src]
pub struct Termios {
// some fields omitted
}Unix terminal I/O control structure.
The Termios structure is a thin wrapper for the OS-specific termios struct. The only safe
way to obtain a Termios structure is to fill one from a file descriptor with
Termios::from_fd(), after which it can be treated just like the POSIX
termios struct. It provides access to the standard fields of the termios struct (c_iflag,
c_oflag, c_cflag, c_lflag, and c_cc) through the Deref and DerefMut traits.
Example
The following is an example of how one might setup a file descriptor for a serial port:
use std::io; use std::os::unix::io::RawFd; fn setup_serial(fd: RawFd) -> io::Result<()> { use termios::*; let mut termios = try!(Termios::from_fd(fd)); termios.c_cflag |= CREAD | CLOCAL; termios.c_lflag &= !(ICANON | ECHO | ECHOE | ECHOK | ECHONL | ISIG | IEXTEN); termios.c_oflag &= !OPOST; termios.c_iflag &= !(INLCR | IGNCR | ICRNL | IGNBRK); termios.c_cc[VMIN] = 0; termios.c_cc[VTIME] = 0; try!(cfsetspeed(&mut termios, B9600)); try!(tcsetattr(fd, TCSANOW, &mut termios)); Ok(()) }
Methods
impl Termios
fn from_fd(fd: RawFd) -> Result<Self>
Creates a Termios structure based on the current settings of a file descriptor.
fd must be an open file descriptor for a terminal device.
