it's amazing what people say! We have adviced and described what type of serial cable should be used. The reason is there are different types with different wiring, like null_modem ones. We use the regular type where each number of pin is wired to the corresponding numbered one on the other side of the cable. So there is no Eventide with wrong numbering of the pins, just people who are using wrong serial cables.
