Dll and mobile problems

I have a 3210 Nokia mobile phone and i would like to have a communication mobile-pc. I have found many programs that do that but i did never found one that doesn't have problems with characters non-english.I have found althouth a dll that can communicate with the mobile. With "Depends" program that comes with vc++ i can see what procedures the dll containes...but my problem is that i don't know their parameters and theri "returns".
So, if somebody can help me, my questions are 2.
A)Is there a way to "see" the parameters of the procedures the dll include?

B)Is there some code(vb or c) that i can use to communicate with the mobile?Any tutorial?
Thanx in advance(and sorry for my english)

your best bet is to go to Nokia.com, they have a developer section which apparently tells you how to do most of the things you could want with their phones...
