problem a bout serial communication...dont receive any response

I have vc0706 camera with rs232 i want to use command for programing but i dont receive any response
witch part has a problem?read or write?

uint8_t bautRate[]={0x56,0x00,0x24,0x03,0x01,0x0D,0xA6};//115200----   

for(int i =0;i < 7;i ++){
Serial.write(bautRate[i]);//

Serial.print(bautRate[i],HEX);
}
Serial.println();
 for (int i = 0; i < 5; i++) { 
      while (Serial.available()>0); // wait for a character   Return:76 00 24 00 00

      uint8_t incomingByte = Serial.read();
      Serial.print(incomingByte, HEX);
      Serial.print(' ');
    }

Please post your code and your results

This ain't quite right:

      while (Serial.available()>0); // wait for a character   Return:76 00 24 00 00

oqibidipo: This ain't quite right:

      while (Serial.available()>0); // wait for a character   Return:76 00 24 00 00

yes...thank you but my problem doesnt solved...

AWOL:
Please post your code and your results

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  //write data
  uint8_t bautRate[] = {0x56, 0x00, 0x24, 0x03, 0x01, 0x0D, 0xA6}; //115200----     0x56 protocol sign --0x00 serial number--0x240301 command--0x0DA6 baderate
  for (int i = 0; i < 7; i++) {
    Serial.write(bautRate[i]); //initialize the camera
    Serial.print(bautRate[i], HEX);
  }
  Serial.println();

//read response
  for (int i = 0; i < 5; i++) {
    while (Serial.available() > 0){ // wait for a character   Return:76 00 24 00 00

    uint8_t incomingByte = Serial.read();
    Serial.print(incomingByte, HEX);
    Serial.print(' ');
    }
  }
}

void loop() {
  // put your main code here, to run repeatedly:

}

Are you using the same port for serial monitor and vc?

You send the baudrate values twice (once as binary, once as text) to the same serial port. Why?

The camera uses RS232 How is it connected to the Arduino ?

I use a converter as an interface

Tell us more. We can't see your workbench.

What converter? Post a diagram showing all the connections.
