Description
Terminal-aware Perl scripts can inspect and change TTY settings without shelling out to fragile command pipelines. This is useful for installers, serial-console tools, test harnesses, and automation that needs predictable terminal modes.
It is a Perl library, not a separate app. Developers use it from code when they need to control echo, raw mode, baud rate, or other terminal attributes. Incorrect settings can leave a terminal hard to use until it is reset.
