WIZ220 Serial Debug Mode

According to the User’s manual, there is a button in the configuration tool to enable serial debug mode. When set, you can monitor the status and socket information through the serial terminal connection.

I’m not seeing anything on the serial port, even though I have the mode enabled and am sending valid packets to the web server. I see the web server is setting the outputs I want, but nothing on the serial port.

Is there something else I need to do to enable this feature?
