This code is one part of a big system, there are 2 microcontrollers talk serially with each others, I write the code for one of them, they send the data from the other microcontroller as follows:
- send a byte (0x41 or 0x42 or 0x43 or 0x44 or 0x05) , I have to check the serial port till I receive this byte, if I don't receive it during certain time , I perform certain code.
- if I received the first byte, and it's really one of the previous values, I begin to receive the 16 bytes data and I have to wait till I receive all of them correctly or the system will not complete.

Now, I can receive the first byte which is 0x41, but I can't receive the 16 bytes data
* I knew that I received it from certain actions in the rest of the system on the simulator "protus"
* I used Keil to dubugg the code and it worked normally but it's not working in the system.
* I replaced the Pointer with the array itself but also it doesn't work. i.e. ==>

R_serial () interrupt 4
        {
	   if(RI)
	      {
		 serialR = SBUF;
		 CompDataRx[count]= serial;
		 ++count;
		 RI=0;
		 
	       }
	   else
		 TI = 0;
	}

void main()
{
	while(1)
           {	     
	
	     SerialInit(9600);
	     SendCompAddress();
	     for(i=0; i<=255; i++)
               {
                 CompState = SerialReceive();
        
                 switch(CompState)
                   {
                    case 0x41:
                          count = 0;
                          while(count!=15);
                          ......
.................................
