inputTTY property
Whether to prefer the controlling TTY (/dev/tty) for interactive input.
This is useful when stdin is redirected (e.g. piping a file into the process) but you still want the TUI to read keystrokes from the terminal.
On Unix platforms, the runtime attempts to open /dev/tty and will use
stty to toggle raw mode for that device.
Implementation
final bool inputTTY;
