My laptop, a Lenovo Thinkpad, is only showing one com port which is Com-4 and I need another com port to run my CNC machine. Com 4 is beening used by my laser machine running LightBurn. Is there a way to "make" a new com port? My Windows 11 is version 22H2.

A USB to serial adapter, maybe?

(Not something I've ever needed.)
