Question about COM port

Can you answer on such a question about COM ports. I have mobile telephone Nokia 6020. I bought cable for him - DKU-5. 
It has USB connector, but in reality it's COM port connector. What i must do to make my telephone visible in FreeBSD? Two ports COM1 and COM2 are free and i suppose that my telehone must be COM3 or COM4. What settings to make? I'll be very pleased if you answer on my question.
