      Look closely above the pins…
      "10101"
      What could this mean?

      ANYTHING
      It’s like an USB, just slower. Also, plug and play, not full duplex though.

      You can use some old and niche joysticks, besides that, it’s borderline useless nowadays.

      Lots of automotive shit with the right adapter cables. I need to get one to hook my beemer up to my thinkpad for a little diagnostics.

        >having a modern cuckbox that has this kind of "diagnostics"
        my car just has a socket where you short out two pins with a wire and then it blinks the CEL in a morse code (or some sort of blink code) pattern and you look up the blinks and that tells you the problem. It just werks. I haven’t even needed to use it yet.

      A lot of devices use that connector for RS-232.
      Control systems can send out remote commands to a network of hardware devices.
      eg. – Press a button on a touchscreen, and all TV’s in the wing of a hospital turn on, and all the audio amplifiers switch their source to the output of your PC.
      Some professional studio equipment refers to that as the "SONY 9-pin," and it’s used to connect transport peripherals to linear multitrack devices.
      People like to think it’s a dead technology, but those people are both wrong and scrotebrained.

      Like USB, but sending data is absically as easy as reading and writing to a file.
      You can use this to talk to many devices in plain text, like oscilloscopes.

      I have a serial console set up on my home server and the computer I use as a router. Has saved me a lot of trouble since if something fucks up I can log in and look at it without having to move the machines out from under the desk or stuff a video card into them to hook up a monitor.

        i forgot my router has a serial port. the only problem is that it’s in a different room and i’m not about to lay a fat serial cable just for that.

      Hook up a vt220 and have a fallback for when your GPU does a lockup.

        that would be nice, if i could afford one.

      You can bit-bang any data into and from any device of your liking, even self built ones. I built a serial EEPROM programmer just for learning purposes.
      Important thing though is, Windows XP is the last OS that works with them, everything after that is not able to properly time the bitstream. Works on Linux though.

      A lot of dev boards have them because you just open a comport in software and literally stream bits back and forth, no packet or network stack bullshit. Also latency on them is really good.

      RS232 is one the most popular communication interfaces. It’s used in so many industries when you need to bidirectional data over a relatively long distance. Heck I almost used it in my audio DSP project where the arduino needed to communicate to a control circuit that was many meters away. Modern motherboards don’t have this port anymore because USB basically replaced it. But that doesn’t mean RS232 is dead. In applications where you only need a few hundred kilohertz of bandwidth over some meters, it is a cheap and reliable way to get it done.

        Most modern motherboards still have it, but only as a pin header on the motherboard.
