Termios Rust Bindings

The termios crate provides safe bindings for the Rust programming language to the terminal I/O interface implemented by Unix operating systems. The safe bindings are a small wrapper around the raw C functions, which converts integer return values to std::io::Result to indicate success or failure.

Project Status

This is a very low-maintenance project. The termios API is decades old. This isn‘t an area that you should expect to see daily commits, so don’t be put off if you don‘t see commits for several years. This just means that the project is stable. That’s a good thing. :)

If, however, you see old patches that you'd like to see land, please see to see how you can help.

Dependencies & Compatibility

In order to use the termios crate, you must have a native libc library that implements the termios API. This should be available on any Unix operating system. This library contains the termios definitions for the following platforms:

  • Linux (x86_64, armv6l)
  • Android (x86)
  • OS X (x86_64)
  • FreeBSD (amd64)
  • OpenBSD (amd64)
  • NetBSD (amd64)
  • DragonFly BSD (x86_64)
  • illumos (x86_64)

If you‘re interested in a platform that’s not listed here, please see to see how you can help.


Add termios as a dependency in Cargo.toml:

termios = "0.3"

Import the termios crate and any symbols needed from termios. You may also need std::os::unix::io::RawFd for file descriptors and std::io::Result to propagate errors.

extern crate termios;

use std::io;
use std::os::unix::io::RawFd;

use termios::*;

fn setup_fd(fd: RawFd) -> io::Result<()> {
  let mut termios = try!(Termios::from_fd(fd));

  termios.c_iflag = IGNPAR | IGNBRK;
  termios.c_oflag = 0;
  termios.c_cflag = CS8 | CREAD | CLOCAL;
  termios.c_lflag = 0;

  try!(cfsetspeed(&mut termios, B9600));
  try!(tcsetattr(fd, TCSANOW, &termios));
  try!(tcflush(fd, TCIOFLUSH));
