[Arduino source code for KC868-A8M]-06 RS485

Code:

#define A8M_RS485_RX 15
#define A8M_RS485_TX 13
void setup() {
  Serial.begin(115200);
  Serial2.begin(115200,SERIAL_8N1,A8M_RS485_RX,A8M_RS485_TX);//A8M
  Serial2.println("A8M RS485 SEND is OK!!"); 
}

void loop() {
  /*print the received data of RS485 port*/
  while(Serial2.available()>0)
   {
    Serial2.print((char)Serial2.read());//Read rs485 receive data  and print it
   }
  delay(200);
}

I want to use serial to show income data but no luck. Serial is empty. Do I need to add code to print in computer serial?
