def rpc_call_raw(self, json_data, send_only=False):
        """
        Send a raw JSON request to the server

        This method does not validate the input JSON. Also you have to make sure
        that if you send a request where the "id" parameter has the value "null"
        the parameter send_only must be True. Otherwise the client will block
        indefinitely because the server sees it as a notify request and does not
        send an answer.

        If we are currently not connected with the server this method will call
        __connect() to create a connection.

        Args:
            json_data (str): The JSON that is sent to the server as is
            send_only (bool): Only send the request, don't try to read a response

        Returns:
            str: The response string as returned by the server
            None: If send_only is True

        Raises:
            NetworkError: Any network error
