Printer is Tronxy. Can not get Cura 3.4 to find the correct port.

Devices manager says that the printer is on USB-SERIAL CH340 (COM8).

How do you set the com port on Cura 3.4.

Settings, Printer, Manage Printers, Pursa I3 MK2, Machine Settings simply reads

the print is not connected.

How is Cura 3.4 set to read COM8?
