For anyone wondering, X-ON and X-OFF are flow control characters. A device sends X-OFF to say "my buffer is full, stop sending data" and X-ON when it's ready to resume.
On most Unix terminals, these have the effect of pausing and resuming the display when a bunch of data is scrolling by.

Oh, thank you. The reference I found[1] only showed them as "device control." I thought I imagined them having that.
Also, the classic control-G is still in C. "\a" is "alert (beep)."
I'm pretty sure every possible combination of 7-bits is assigned SOME name in ascii, and Ctrl-any-case-insensitive-letter is a defined 7bit value.
This chart says control-s is `DC3 (Device Control, X-OFF)` and control-q is `DC1 (Device Control, X-ON)`. Yup, that's what they do alright.

Don't forget everyone's favorite control-G, BEL, useful sending beeps across the wire on old school IRC, BBSen, and chat services. Or, you know, telegraph machines or something.
