Tera Term not working

I am using the Basic DA14580 development board, following instructions in UM_B_025 DA14580_581_Bluetooth_Smart_developement_kit-Basic V2.2, using Keil 5.15. The Blinky example runs on the board fine, i.e. LED blinks. However, the Tera Term is not showing any output. I am connected through COM9, Jlink CDC UART port in the drop down. The appearance of that in the dropdown should indicate it's detecting the device correctly, but yet no output in the terminal.

任何建议吗?谢谢你！
