Thanks for confirming my guess. I remain amazed that serial connections are used so much in amateur radio. Outside of amateur radio, I’ve used RS-232 connections once since the early 1990’s. In 2002, I connected a console to an HP-UX to rebuild the kernel and get it on our net. I threw away all my RS-232 connector building stuff a decade ago. Then I got into amateur radio.
