I cant get this working - I have only 3 wires cable, and I cant get this 3.3V wire.
I put this to work as home router and my friend do not have any problems with it.
You may search fonera forums for info about building com port.
I believe that this pinout is the same.
If you need any help - I’ll make what I can.
Success!
