3. Under the “Ports Setting” tab
shown click on the “Advanced”
button near the bottom of the
window.
d. Another window will appear
as shown. Click on the drop
down menu beside “COM Port
Number” and choose a serial
port between COM1 and
COM8. There are two things
to keep in mind when
selecting a port:
a. Make sure you do not
select a physical port.
A desktop usually has
one serial port and
COM1 is reserved for
it. If a PC has two physical
COM parts COM2 would
usually be reserved as well.
b. In the drop down menu sometimes you will see “In Use” in
brackets beside some of the COM port selections in the list. It is
Ok to select one of these if you do not have any other USB
devices that use virtual COM ports plugged into your computer.
Once you have selected the COM port click the OK button in the top right
hand corner. In this example COM3 was selected.
