Sample apps serial terminal I/O - no output on FRDM-MCXC041 eval board

Newb here. Looking to transition from Microchip/Atmel environment, so I got the MCXC041 eval board and tried to load the hello world or LED control sample app from the MCUxpresso ide. I am able to connect to the board and debug single step in.over lines of code, but when I connect to the serial terminal for I/O from the sample apps, there is NO activity. In the case of hello world I expected a printf "hello world". In the case of LED control app, I expected to be able to type in "led 1 on" or similar command

Hello @diyguy88,

Could you please configure your serial terminal according to the instructions provided in the example_board_readme file for each example? You can find this document inside the doc folder of the project.
This document also describes the functionality of each example and outlines the expected output you should see on the terminal once everything is set up correctly.
Additionally, please keep in mind the recommendations listed in the README file for each example to ensure proper operation.
If you experience any issue, do not hesitate to let me know.
