Now verify that the serial connection is operational. You can do this using a serial terminal program by checking if you get any output on the terminal after resetting {IDF_TARGET_NAME}.
.. only:: esp32c2
The default console baudrate on ESP32-C2 is 115200 when using a 40MHz XTAL, or 74880 when using a 26MHz XTAL.
.. only:: not esp32c2
The default console baudrate on {IDF_TARGET_NAME} is 115200.
Windows and Linux
^^^^^^^^^^^^^^^^^
In this example we will use `PuTTY SSH Client <https://www.putty.org/>`_ that is available for both Windows and Linux. You can use other serial programs and set communication parameters like below.
Run terminal, set identified serial port, baud rate = 115200, data bits = 8, stop bits = 1, and parity = N. Below are example screen shots of setting the port and such transmission parameters (in short described as 115200-8-1-N) on Windows and Linux. Remember to select exactly the same serial port you have identified in steps above.
