So back in the day, perhaps over a decade ago, I remember stumbling upon a textfile that was along the lines of "interesting IP addresses on the net" (does anyone know what I'm talking about? I can't find it since.) and one of them was a very curious telnet console that had all sorts of settings. Googling the terms, it looked like it was the control panel for a microwave antenna. I was too scared to mess with it though. I only remember exploring through the menu options. I never figured out where it was or what it did, but I remember it was surprising to me at the time that standalone hardware would have a telnet terminal.
