KSON,

In this case, you are more than likely going to have to access the modem
through the RAS API. To access this API, you will have to call the
functions through the P/Invoke layer. You can find more information on the
RAS API here:

You also might get some help with the function/structure declarations
from http://www.pinvoke.net.
