i was assigned to to build a home automation system, using phone and communication with pic16f877a. I am able to direct the pic to send out message but i really have a trouble to read the response from the phone(gsm modem). For instance, when i direct pic to sent "AT" to the gsm phone, it should reply "ok" but instead it reply"AT" too(i make it to display the result on LCD). i try to make my array to receive more character but after the second character, the LCD display jammed. PLease help me!! i am so out of idea now.
