serial terminals not working properly

Hi!

I want to set up transmission between two boards P-Nucleo_wb55. When I firmware blink using cubeIDE example

(\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_CableReplacement)

But after opening serial terminals on system, COM ports appears but they don’t give feedback.

Kindly help me out.

Thanks
