By default, gotty doesn't allow clients to send any keystrokes or commands except terminal window resizing. When you want to permit clients to write input to the PTY, add the `-w` option. However, accepting input from remote clients is dangerous for most commands. Make sure that only trusted clients can connect to your gotty server when you activate this option. If you need interaction with the PTY, consider starting gotty with tmux or GNU Screen and run your main command on it.
