Virtual Com port not working with CubeIDE and ST-Link?

I am attempting to debug an Azure RTOS example (NX_TCP_Server_Echo) but I am not receiving any messages on the VCOM port. In device manager I can see that the STLink Virtual Com Port is assigned to COM8 at 115200 bps. So I attach my Hercules Setup utility to Serial COM8 at 115200 bps. But when starting the debug session I receive no messages. So I cannot attach remotely to the target server application.

Is there some magic configuration parameter that needs to be set in order to use the VCOM port?

Hi Mike,

if not done yet, I suggest you to start with this example which is included in
