B-U585I-IOT02A demo serial port can receive but not transmit data

Hello. I just started with the B-U585I-IOT02A ("Discovery kit for IoT node with STM32U5 series") board. When I run the out-of-the-box demo, plug in the micro USB, and setup the serial port, I can see the "STM32U5 Webserver Demonstration" banner, the network scan results, and the "Please enter your wifi ssid" message, but I cannot see any text that I type into the terminal. The terminal doesn't seem to to respond to anything I type. Am I missing something here?

I have tried TeraTerm and PUTTY on Windows 11.

Thank you!

    There may be more to it, but in case someone else runs into this, I did the following in TeraTerm and it seems to work. In setup-->terminal:

    1. Set newline transmit to "CR+LF" (not just "CR")

    2. Turn "Local Echo" on.

    If there's something else going on here other than picky parsing and no echo, please let me know.

    Thanks!
