closeStdin method

@override Future<void> closeStdin()

Signals end-of-input on standard input (half-close).

Implementation

@override
Future<void> closeStdin() async {
  // A pty has no half-close; deliver Ctrl-D so the line discipline signals
  // end-of-input to the foreground program (mirrors the script PTY session).
  writeStdin(const [0x04]);
}
