"I have no idea how your "polling" device works, but with RS-232, there is no polling, "

Point 1 is true. Point 2 is, in my opinion, not true.

A poll is a request for information.  The device issuing the poll/request is the polling device.   For example, sending IF; to a TS-590 is a data request, or poll, for the current IF status.  The TS-590 responds with the full IF word.
