You might want to consider this product. I have used a very early version of it and think it might be what you're looking for. https://www.hhdsoftware.com/serial-port-monitor

Thank you both.

The second seems a bit more complicated but more loaded with features.

Hi Ioannis

The serial port monitor software sits on top of your existing serial port driver on the same PC which communicates with the device. So, you can run your PC software with your device and intercept all the traffic passing to / from the device.

Therefore, whatever traffic passes through the serial port on the PC, it can intercept and display.

Yes, it is a great tool! Thanks,
