AT Commands Problem

Hi, i am trying to send AT commands to a k300 sony erricsson cell phone and then reading the response. Now i have done the sending part which is to send commands to the cell phone and is working perfectly but i want to see the response, i.e "OK", to be saved in a variable or something. I tried the uart method and serial transfer direct method with own functions method and in both i can transmit the data but never receive the "OK" Can anybody please help me.

    How do you know that?

    "i can transmit the data but never receive the 'OK'"

    How do you know that the K300 actually sends the OK?

    Are you certain that you are using all the correct signal levels on all the required lines?
