terminology poll: what would you call the part of the operating system that is responsible for managing the pseudoterminal device? (handling ioctls, tracking the foreground process, remembering the terminal window size, turning `Ctrl+C` into a SIGTERM, handling `Ctrl+S` and `Ctrl+W`, etc)

(also open to hearing that you think that it's not just one thing or anything else really)

all of the code for this stuff (terminal ioctls, process groups, window size, signals, Ctrl+W, etc) in Linux seems to be in `drivers/tty` which kinda makes me want to call it this component the “TTY driver" (which helpfully implies the existence of a TTY device, which is an important thing)

(2/?)

@b0rk "TTY driver" because on some level this thing still thinks it's puppeting a VT100.
