I am currently working on a friend's note-book, but all the port numbers (ie. com1 etc.) seem out of the ordinary. How do I find out which port is which?

To check out the assigned ports,you need to right-click on My Computer,in Device Manager pane at the top highlight Computer and then click the properties button,at the botom of window.

You can also mechanically test which port is which, by attaching an external device (such as an external modem) to the com port (with the computer powered off) and then power up the computer and see if Windows detects the modem.

You cannot harmyour ports by trying to connect to a device that is not there. After connecting/detecting a device, it should be clear with port is com1 and which is com2.
