problem with receiving frame in arduino

hello,

using 2 arduinos send frame example 1 arduino using serial library
here transmitter code:

code: [select]



void setup() {
    serial.begin(9600);
}

void loop() {
    
    serial.write(0x7e);
    serial.write((byte)0x0);
    serial.write(0x10);
    serial.write(0x17);
    serial.write((byte)0x0);
    serial.write((byte)00);
    serial.write((byte)00);
    serial.write(0x48);
    serial.write(0x45);
    serial.write(0x4c);
    serial.write(0x4c);
    serial.write(0x4f);
    serial.write(0xff);
    long checksum = 0x17 + 0x48 + 0x45 + 0x4c+ 0x4c + 0x4f + 0xff ;
    serial.write(0xff - (checksum &0xff));
    
    while(serial.available());
    serial.write(serial.read());
    delay (500);
    }


and here receiver code:

code: [select]


void setup() {
  // put setup code here, run once:
 serial.begin(9600);
 
}
void loop()
{
  if (serial.available()>=13){
    if (serial.read()==0x7e){
    
        
    
    for(int i=0;i<13;i++){
      serial.print(serial.read(),hex);
      serial.print(",");
         }
         serial.println();
  
}}}


the simulation on proteus isis gave me results:

in reception want display red zone how eliminate others???
please thank

in reception want display red zone how eliminate others???

the simplest way not send them. why sending them?
