Switches the terminal out of raw mode. Raw mode is similar to cbreak mode,
in that characters typed are immediately passed through to the user
program. The differences that are that in raw mode, the interrupt, quit,
suspend and flow control characters are all passed through uninterpreted,
instead of generating a signal.
