I have a symbol device that has an inbuilt GPRS modem. I want to connect to
a webservice from the compact framework.

I dont want to have the connection settings entered on the device because it
will allow people to use this connection for things like explorer.

My current routes of exploration have been:

1. Use OpenNETCF.Net.ConnectionManager
But this I believe needs to have an entry in the connections to connect so
thats not valid for my design limitations.

2. Use OpenNETCF.IO.Serial
I believe that if i send the correct strings eg (AT+cddcont=1,"IP","blah"
then ATD*99#) down the modem then this will give me an IP address once it
connects. But i never seem to get any response but am I barking up the wrong
tree.

Any help would be appreciated.

First check using a connection (enter dial commands manually) that your
AT commands are correct.

Your 2nd option should work. After all this is what all terminal
programs do. Sending AT commands to the port.Just make sure that you
send the correct commands to the correct COM port.

I think that if you check the registry under ext. modems you will find
an entry "Virtual GSM on COM8" and a "Virtual GPRS on COM9" (or
whatever). Use that COM port.


Good luck
