RS232 is still pretty common with the electronics hackers.

A lot of modern embedded computers such as modems/routers have a TTL level serial port somewhere on the board. It's nice to have an extra way into the machine if its network is down, for example.

or you can make one in software.

Or software-as-hardware when programming FPGAs. Many FPGA boards have one traditional RS232 port, but it's only provided with voltage converters, so you need to program the actual signaling logic. But if you only need TTL level signals, you can skip the traditional voltages and use plain FPGA pins.
