Hi All!, I'm doing research for my thesis, I was wondering... 1)Is it possible to send an SMS, while calling someone and sending data all the three at the same time using different GSM channels for each one? 2) Is it possible to send data on the voice channel? 3) Is it possible to send voice on the data channel? In any case code example will be really appreciated! Thanks you very much! Kind Regards. Guillermo.
