A user types at a terminal (a physical teletype). This terminal is connected through a pair of wires to a UART (Universal Asynchronous Receiver and Transmitter) on the computer.

Once I had the opportunity to sit at such a machine.

A real typewriter with real paper. And no display! Only paper.

I type my “command line” and it appears on my paper. Ok, where else…

The computer responds by letting it’s response appear - what do you think? - on my paper, too. Not by magic, but by my machine typing it.

I am typing to my paper. Then the computer is typing to my paper. And so on.

Hardly ever have I had such a creepy feeling while doing computer work 😵‍💫

I haven’t used one as a tty, but my father had a typewriter like that.

He’d feed in forms for invoicing and software would have the typewriter fill in values in the right fields of that form.

I’ve had vt220/320/520 terminals back in the day. Been itching to source one now that I have a forever home to store crap like that, but they’re becoming quite rare and expensive.
