How do I identify what Com Ports are available on my computer?
If using the 9 pin “To comp” adapter, the port will most likely be assigned to Comm 1. If plugging into the computer with a USB, then the device manager will list what comm ports are being used.
Select the start menu and RIGHT CLICK “Computer” or “My Computer”. Select the last option in the dropdown – “Properties”.
2. If using a Windows XP machine, select the “Hardware” Tab to select “Device Manager”. Otherwise, select “Device Manager” on the left side of the screen.
