You could build a database of various quirks that are required for each =

model.  The index into the database could be the product id if it is =

unique, or the model / revision information from 'ATI"

Another idea would be to have the gprs context driver try to parse the =

AT+CGDATA=3D? response.  If 'PPP' L2P is not found, then fallback to using =

ATD*99.
