I'm developing an embedded Visual C++ application that could connect with a phone/modem GPRS and I tried the RAS Function, the application should work in PPC 2002 and PPC 2000 (I mean, the Connection Manager API, is not valid solution for PPC2000) , but I can't find the way to specify the APN (+cgdcont ...) in the RAS Function.
Does anybody know how to include the specific GPRS commands (APN,...) using this functions?
Thanks in advance

Two things ...
1. if you can get a ras connection going, then why not just send the at command via the serial port?
2. on PocketPC you probably want to look at the Microsoft CellCore API - this is the new API that incorporates the cellular interfaces you are looking for. You can find this in the PPC Phone Ed and Smartphone SDK's from Microsoft.
You need to pass the APN to the handset in the form of a modem initialisation string. In Control Panel select the "modem" that is used by Windows (in my case this is a default 28800 baud modem), find the place where you can enter something like "Extra Settings"
You need to enter something like:
&K3;+CGDCONT=1,"IP","mobil
The APN here "mobile.o2.co.uk" is for the "O2" network in the UK.
You will also be able to get to the modem in use via your Dial-Up Networking icon.
NOTE: On some versions of Windows it is not possible to add a string of this length in the field, in this case add a memorable string (like "hello mum") and then search for it in the Registry. When you have found it edit the entry to the required string and DO NOT try to change it in the modem setup again.
Hope this helps

For an project we are using Siemens TC35 Module which is integrated with an device(built specifically for our project by our clients). The TC35 Module is connected with the device through the serial port.
Now when i load the SIM Tray with the SIM card & switch on the device(integrated & interfaced internally with TC35), & send an command "AT", It gives the response "OK", But now I make an call to an the SIM card number from my personal mobile. My Mobile says that the "Number you are Trying is Switched OFF". Iam very much Confused wether the device is witched on or off. Can you help me what I have to do. Also when I tried with "COPN", "CGMR", "CREG", "COPS"commands, I get the "ERROR" messages. So Kindly help me.
Iam in very urgent position. Also if any one can send me an sample source code to GSM communication for Dialing up an ISP connection & connecting to an Server, It would be greatly helpful to me.
Waiting for your reply.

I thought that the special commands were included in the .inf file. See MSDN DDK Modem Devices Protocol\GSM.
