If I should put this in another forum, my apologies. I *think* I'm alright since this is very much directed towards GPRS especially.


I'm writing a program in C++ that will access the internet. Unfortunately, my program needs to be aware of when a connection is going to be stopped. Class B devices, I've read, suspend data when a voice call comes in, while Class A can do both at once. If a device my program is running on is A, I won't need to worry about anything, but if it's B... Well, something needs to be done.

Is there any setting or property on devices that directly says whether it is Class A, B, or C?

You are correct that devices have different classes... I would assume that all devices are Class B for effect of development. I don't remember of ever seeing any Class A device in the field.

Note this is only for GPRS and EDGE though, not including UMTS/WCDMA. If you have a UMTS/WCDMA device, you can assume data connections will continue when a voice call comes in. However this is only true for internal connections, not when the device is used as a modem.
