Struct TtyDevice

pub struct TtyDevice {
    name: &'static str,
    uart_device_id: usize,
    input_buffer: Arc<Mutex<VecDeque<u8>>>,
    input_waker: Waker,
    canonical_mode: bool,

}

TTY device implementation.

This device provides terminal functionality including line discipline, echo, and basic terminal I/O operations.

Fields

name: &'static str

uart_device_id: usize

input_buffer: Arc<Mutex<VecDeque<u8>>>

input_waker: Waker

canonical_mode: bool

echo_enabled: bool

Implementations

impl TtyDevice

pub fn new(name: &'static str, uart_device_id: usize) -> Self

fn handle_input_byte(&self, byte: u8)

Handle input byte from UART device.

This method processes incoming bytes and applies line discipline.

fn echo_char(&self, byte: u8)

Echo character back to output.

fn echo_backspace(&self)

Echo backspace sequence.
