That may be what the DISCUSSION showed, but that's NOT what my QUESTION
asked (which was how one might connect two EPP ports so they could "talk"
with each other bidirectionally).

Others "answered" the question by suggesting alternative solutions
(And there is/was nothing wrong with that!),
but only a very few actually addressed the original question,

And I hereby thank them.
