Me too; particularly as I've been using them quite a bit recently; AT lives on in embedded system network comms (e.g 4G, wifi, ethernet and/or bluetooth modules - the ESP32/ESP8266 has AT command support). It's really expanded a lot these days - you can do http(s) and mqtt requests, and even run a web server without having to touch a TCP stack.

I remember feeling like a magician when I first learned about AT commands. It was my first real experience getting the computer to do something physical. After that, I learned about all the IO accessible on the parallel port, allowing full binary access to the real world. I was hooked, and it eventually led to a career of making computers do physical things. :)

Super disappointed that this is not about modems...

Not me, but only because you saved me a click. "Go to the comments first", FTW. :-)

(Though I might still waste that saved click just to see what TFA is about...)

Clicked on the link looking for a blast from the past, came away bewildered.

IBM PC/AT keyboard protocol here. But it is more often called "PS/2", which is the same with more keys.

Me too. Wikipedia seems to have a decent list: https://en.m.wikipedia.org/wiki/Hayes_command_set

Same here. I think most of us old beards had the same reaction.

Yes. Perhaps like Telegram refers to an important earlier communication medium.

It's not just you.

That's what I expected as well.

Not just you.
