No serial seen by Nokia 6234

Hi all, i've installed comproxy in my pc and it woks on COM6 where is available an USB connection with my phone.
When i try to set the connection on my phone i can see bluetooth/serial on menu but when i select serial ports a "No serial port" message appears.....
How can i set up it correctly?
Why cannot be downloaded already packetized maps for a specific region?
Can i download a map of another town then mine?
Thank you.

serial port

you have to use bluetooth on your phone. serial port on your pc. port which is mapped to bt incomming. I will rewrite this comproxy app not to use serial ports for easier using.
