Tapi Initialize() and tapi.GetDevCaps(deviceID, out dc)

Hi all,

what should return Initialize()  and what is the meaning of deviceID in GetDevCaps ?

I used the library to get the radio signal strength on Win Mobile 4.2; this line works with deviceID = 0:

tapi.GetDevCaps(deviceID, out dc) == 0)

 and dc.ProviderName returns "Cellular TAPI Service Provider",

but I can also use device = 1 or 2,3 ecc which instead makes dc.ProviderName returns "UNIMODEM".

Where are defined this costants and what are the meaning ?
