In the Raspberry Pi OS, users can enable access to the serial interface through the [`raspi-config`](https://www.raspberrypi.com/documentation/computers/configuration.html#raspi-config) configuration tool. The tool can be utilized through either the CLI or [desktop GUI](https://www.raspberrypi.com/documentation/computers/configuration.html#raspberry-pi-configuration). To change the configuration settings, users will need to navigate through the [Interface options](https://www.raspberrypi.com/documentation/computers/configuration.html#interfacing-options) > [Serial port](https://www.raspberrypi.com/documentation/computers/configuration.html#serial) menus and enable the serial port.
