Represents the readable side of a TTY. In normal circumstances process.stdin will be the only tty.ReadStream instance in a Node.js process and there should be no reason to create additional instances.

Represents the writable side of a TTY. In normal circumstances, process.stdout and process.stderr will be the onlytty.WriteStream instances created for a Node.js process and there should be no reason to create additional instances.

The tty.isatty() method returns true if the given fd is associated with a TTY and false if it is not, including whenever fd is not a non-negative integer.
