In ramses_rf, Gateway, which is a subclass of Engine, we have is_hgi80():

class Engine:
    def __init__(
        self,
        port_name: str | None,
        input_file: TextIOWrapper | None = None,
...
    ) -> None:
...
        if input_file:
            self._disable_sending = True
        elif port_name:
            is_hgi80(port_name)  # raise an exception if the port is not found

I believe it is fixed.
