I am currently doing a project related to GSM and I have problem running a GSM related program which is done by previous student. I try debugging it and discovered that the pointer run till the "Red coding" and it stuck there... I have check the value of RI and 0ACount[4], both value is 0. But it still not moving to the next part of the program. In other word, i need to run the program to run and exit to the next loop. (I want to state that i do not really understand this program but it has been tested by previous student) Any kind soul and help me on this. Thanks inadvance to those who reply and help.
