The way to figure out which serial port on the back
of the PC corresponds to which COM port is to use the
world's cheapest piece of test equipment...the lowly

Check each 'COM' in turn - and you'll soon find which
COM corresponds to which physical socket.
Bear in mind that if you have a Modem card in your PC,
it may appear as COM3 or COM4 or something.
