How can I open a virtual port?

Hello All,

How can i open a virtual port (ADL_PORT_USB_VIRTUAL_BASE),in ADL User guide is witten that “Please refer to AT+CMUX command & 27.010 protocol documentation to know how to open/close such a logical channel.”

Did someone use before an example of openning a virtual port ?

Thank You.
Best Regards,

So - did you do that :question:

No, I didn’t find something about, did you already open a virtual port before ?
