The pc might also have other serial port devices.
It's pretty much up to you to know which com port you want to use.
I did a project using bluetooth modem and the computer had a few serial ports and i had to figure out which one to use. so i opened each one in turn sending AT command and looking for OK response from the modem.

in control panel/phone and modem options/modems shows that my nokia phone is atteched to com3,but with scomm32 i got port number is com34. | |
