Reading xBee with Arduino Wireless Proto Shield

Hi.
I'm trying to read RSSI of received signal from xBee.
I wrote this code:

#include <SoftwareSerial.h>;
SoftwareSerial mySerial(10, 11);  // RX, TX

int rssi;

void serialFlush()
{
  while(mySerial.available() > 0) 
    char t = mySerial.read();
}   

void setup() 
{
  Serial.begin(9600);
  mySerial.begin(9600);
}

void loop() 
{
  rssi=0;
  if(mySerial.available())
  {
    serialFlush();
    mySerial.print("+++");
    while(!mySerial.available());
    serialFlush();
    mySerial.println("ATDB");

    while(mySerial.available())
    {
      rssi = mySerial.read();
      Serial.print(rssi);
      Serial.print("   ");
    }
    Serial.println("");
  
    mySerial.print("ATCN");
  }
  delay(1000);
}

And i see these output from serial monitor:

26   57   13   
13   156   195   
26   156   13   
26   78   195   
26   57   13   
26   57   13   
26   80   195   
26   156   13   
26   57   13   
26   50   68   13   
26   50   67   13   
26   153   81   195   
26   50   65   13   
26   50   56   13   
26   50   56   13   
26   50   57   13   
26   51   48   13   
26   49   57   13   
26   76   
26   49   65   13

Which is absolute non-sense. It should return only one byte (usually negative integer)
On other xbee i'm just posting "hi" messege to the air and also i'm changing the module's position but i could not find any sequance (during the experiment, the distance is always increased.).
and als ATCN command is not working. I need to wait about 3-5 (no sure) seconds to receive another message.
can anyone help me?

Assuming that you get the RSSI value, after getting the XBee into the proper mode (why you do not print the reply that it makes to the +++ command is mystery), what do you intend to do with that value?

Using it to determine how far apart two XBees are is not going to happen.
