[Elecraft] "Serial port is closed"

[K9SW]

Hello, Elecraft -

Working on getting the K3 hooked up to a Dell Latitude laptop but can’t seem to make a connection using the K3 Utility.  Using the serial to USB adapter cable.   On the K3 Utility port page, no ports show up, and there is a notation at the bottom, “Serial port is closed”.  

Do you have any suggestions for how to proceed in making a connection?

Thanks,

Dave K9SW
