Specify COM port
When prompted for the COM port number
being used, make sure to select the correct
one. If you only have one physical com port
in your computer, this will probably be COM
1 However, if you're unsure, contact your
computer/motherboard manufacturer.
In the case above, we have several COM ports available, and we are using COM 1.
