Click the 

Advanced

 button to show the advanced property settings for the port.

8. 

Select a 

COM Port Number

 in the range of 1 through 16. If possible, select a port which is NOT marked as 

“in use” in the COM Port Number list. If all of the ports are marked as being in use, select port number 
16 unless you know for sure that something is actually using COM16.
