问pc中的Xbee explorer与arduino中的Xbee通信

// We'll use SoftwareSerial to communicate with the XBee:
#include <SoftwareSerial.h>

SoftwareSerial XBee(10,11); // RX, TX

void setup()
{
  // Set up both ports at 9600 baud. This value is most important
  // for the XBee. Make sure the baud rate matches the config
  // setting of your XBee.
  XBee.begin(9600);
  Serial.begin(9600);
}

void loop()
{
  if (Serial.available())
  { // If data comes in from serial monitor, send it out to XBee
    Serial.println("first if");
    XBee.write(Serial.read());
  }

  if (XBee.available())
  { // If data comes in from XBee, send it out to serial monitor
    Serial.println("second if");
    Serial.write(XBee.read());
