Hi and thanks for the explanation, but I am not quite getting it
First - using the [Split] tab
COM 4 is SiliconLabs CP210x USB to UART...
I have added a Virtual port COM14
Then click [Add split port] and get an error. I've tried it a few times.

Attached screen shot.
Then using the [Share] tab and get similar result that "Cannot split this port"
Maybe one of the differences is I have a USB logger, and you Serial?
Disappointing...
