Today I learned about Control-S and Control-Q… better late than never, I guess 😉

And just got me thinking about that helpful “scroll?” at the bottom of my ZX Spectrum after printing a screenful of content in BASIC…

@juandesant Will it freeze the execution of the current command, or only the output?

@ViSzKe @juandesant It pauses terminal output. Processes will keep running until they try to output something. Then they will be blocked, but buffering might delay the effect.

This feature is a remnant from old times when physical terminals would use these characters for flow control.

@juandesant Well, someone saying they never needed it reveals their age.

And it also reveals something about my age, since I have had the need for it.
