What is tty mode?

TTY stands for Teletype, which is a commonly used telecommunication device that allows users to interact with a computer system in text mode. TTY mode is a feature that allows users to communicate with a computer system using a text-based interface.

In TTY mode, users can send and receive text commands to the computer system through a terminal or console. This mode is commonly used for troubleshooting, system administration, and programming tasks.

TTY mode is often used in Unix-based operating systems, where users can access the system through a terminal emulator or a physical TTY device. It is particularly useful for remote access and allows users to perform various tasks without the need for a graphical user interface.

Overall, TTY mode provides a simple and efficient way for users to interact with a computer system using text commands.
