enfora RIL driver CE 6 - how does it communicate with Cellcore, RILProxy

Hi all,

I am curious about enfora sample RIL driver and how does it work internaly.

How cellcore and rilproxy fit into the code execution between client
application and RIL driver?

enfora sample uses serial port. I have seen RIL driver which uses USB port
(Virtual COM port). Enfora exposes WindowsCE stream driver interface through
COM_Init, COM_Open,... functions. Other driver I have seen exposes VDA_Init,
VDA_Open,... functions.
How driver manager knows which function to cal? (VDA_Init() or COM_Init).
Rephrase the question: How driver manager knows which stream interface is
exported by particular RIL driver?

What is the sequence of calls into RIL driver when connection manager opens
GPRS connection?

I would appreciate link to documentation or short answer which will help me
to find further information.
