Terminal Settings for console output

I have built and flashed the example in nrf/samples/wifi/shell

I am connecting to the device on port /dev/ttyACM0

With the terminal settings in minicom as below

These should be correct according to you documentation referenced in other places , for example here : https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Flib_cli.html&anchor=lib_cli_terminal_settings

I am not seeing any output. Is there some key sequence or other trick to this ?
