It might be old and slow, but I love RS-232. It works on every platform, you can write a client or server in just about any programming language in a handful of lines (and understand what they all do). I’ve literally made working RS-232 connections with paperclips and scotch tape. After the corpo wars when we’re all computing on salvaged tech you’ll come to appreciate it.
Not just programming languages either, the hardware side is dead simple too. You can literally implement it in a few lines of VHDL or similar language on an FPGA.
It's like telnet, I'm happy to know its there when I need it but I'd rather not need it.
