2 :name: Native TTY UART
5 Use native TTY driver to send and receive data between two UART-to-USB bridge dongles.
10 This sample demonstrates the usage of the Native TTY UART driver. It uses two
11 UART to USB bridge dongles that are wired together, writing demo data to one
15 :zephyr_file:`samples/drivers/uart/native_tty`.
17 You can learn more about the Native TTY UART driver in the
18 :ref:`TTY UART <native_tty_uart>` section of the native_sim board
24 #. Two UART to USB bridge dongles. Each dongle must have its TX pin wired to the
