Hi there,

I'm a newbie and tried to dial a no from MCU (16F887) to Sony Erricsson K750i. With hyper terminal connected with data cable to pc it works AT commands fine.But I couldn't communicate SE750i with MCU. I have attached schematic I used (drawn by me) and the flowcode program that I used. Please help me to get this done, really appreciate.
