How do you send an AT command to the XBee now? You type some text into an application that sends the text to the XBee via the serial port. So:

Serial.print("ATDB");

Then, the application shows any serial data that came back:

while(Serial.available() > 0)
{
   char inChar = Serial.read();
   // Do something with inChar
}

If the Arduino is using a software serial port to talk to the XBee, replace Serial with the SoftwareSerial instance name.
