pub fn read_output(&mut self, timeout_secs: f32) -> Result<(String, bool)>

Read output from the PTY with timeout

Returns (output, is_complete) tuple where is_complete indicates whether the command has finished (prompt detected)

pub fn send_interrupt(&mut self) -> Result<()>

Send Ctrl+C (interrupt) to the PTY

pub fn send_eof(&mut self) -> Result<()>

Send Ctrl+D (EOF) to the PTY

pub fn send_suspend(&mut self) -> Result<()>

pub fn send_text(&mut self, text: &str) -> Result<()>

Send text directly to the PTY (for interactive input)

pub fn send_bytes(&mut self, bytes: &[u8]) -> Result<()>

Send raw bytes directly to the PTY.

pub fn send_special_key(&mut self, key: &str) -> Result<()>
