This takes one argument, an `interact` function, which is called for each connection. This should be an asynchronous function that runs the prompt_toolkit applications. This function runs in an `AppSession`, which means that we can have multiple UI interactions concurrently. Example usage: .. code:: python async def interact(ssh_session: PromptToolkitSSHSession) -> None: await yes_no_dialog("my title", "my text").run_async() prompt_session = PromptSession() text = await prompt_session.prompt_async("Type something: ") print_formatted_text('You said: ', text) server = PromptToolkitSSHServer(interact=interact) loop = get_event_loop() loop.run_until_complete( asyncssh.create_server( lambda: MySSHServer(interact), "", port, server_host_keys=["/etc/ssh/..."], ) ) loop.run_forever() :param enable_cpr: When `True`, the default, try to detect whether the SSH client runs in a terminal that responds to "cursor position requests". That way, we can properly determine how much space there is available for the UI (especially for drop down menus) to render.
