Hi , Im trying to interface T290i erricsson to a microcontroller , i've the datacable , AT commands works fine in hyperterminal , but i get rubbish charachters when i interface it to the uC and display the results on the LCD , i've used the free serial port monitor , and i've seen that RTS and DTR are green ( blinked) , and the datacable is connected to the uC RS232 which is a two transistors level shifters , i dont know where to connect RTS and DTR ?
