Assuming it's RS232, it is.

A serial terminal with an old Minitel (shit's cheap in france for some reason, even does color) or VT100 (good luck) or something. Or if you're into it, PPP and/or serial communication over radio.
>shit's cheap in france for some reason, even does color
to boost its adaption the French gov gave millions of them for free to citizens.
actually, its technically illegal to sell them as they were loaned for free and not gifted, so they're the property of the french gov. not that anyone cares tho.
>so they're the property of the french gov
No, they were the property or France telecom (which then renamed itself as Orange), which have been the result of the split and privatization of the PTTs in 1989, but before the TRANSPAC network shutdown, they just gave away the leased units to whoever was in their possession so that they woudn't have to pay for their recycling.
Also the State and the gov are two different entities.

Color models aren't cheap, they were sold to businesses and are way harder to find. Your average leased minitel only has a monochrome tube.
Don't pay more than 10€ for one unless it was a sold model (not all models would be leased).

French Ânon here. Americans routinely say "the governement" when we say "the state", and "the administration" when we say "the governement". Sad!
>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 moronic.
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 fricks 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.
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.
Cum in it
talk to serial devices like switches
what kind of switch?
managed network switches
Nintendo
nothing
t. zoomie
Look closely above the pins...
"10101"
What could this mean?
21
lolol ur wrong kiddo
I always thought those were plates and cutlery
ANYTHING
It's like an USB, just slower. Also, plug and play, not full duplex though.
>ANYTHING
Because EVERYTHING comes with one of these ports?
It did, 15 years ago.
And EVERY motherboard has a header to conmect one of these ports.
I use it almost everyday.
>And EVERY motherboard has a header to conmect one of these ports.
Yes, I know. I just got given a bracket for it.
Now tell me specifically what kind of devices connect to this port, because I have no idea.
Computers and peripherals.
Barcode scanners for example.

Where can I find a cheap serial terminal?
eBay most likely, I'm planning on getting a small color one to experiment. Also garage sales if you're lucky.
Didn't know they got it for free, that explains why it's cheap then as french second-hand is basically first-hand prices usually
I guess "cheap" still means £100+. Maybe one day.

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

Connect a serial mouse to it.
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.

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.

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