The 'line buffering' of `tty`s applies to the input to the `tty` (IE. the keyboard) before it goes to the program - basically, the kernel will buffer characters you typed and not send them to the running program until you hit the `eol` character. On the output side the kernel just handles characters as they come in without any buffering/waiting.
