SM5100B-D TCP/IP ERROR

I’m getting lots of errors trying to use your SM5100B-D shield in order to connect to my website. I’m following all the instructions of TCP/IP document you provided at product’s page. Here is my simple test and results:

First of All:

I ‘ve set GSM shield pin D2 to Mega pin 19, and a jumper from GSM shield pin D3 to Mega pin 18.

 ARDUINO CODE: (MEGA 2560)
 #include <string.h>
  
 char incoming_char=0;
  
 void setup()
 {
   //Initialize serial ports for communication.
   Serial.begin(9600); // for terminal communication
   Serial1.begin(9600); //  for GSM module communication
   Serial.println("Starting SM5100B Communication...");
   delay(5000);
 }
  
 void loop(){
   if(Serial1.available() >0)
   {
     incoming_char    = Serial1.read();
     Serial.print(incoming_char);
   }
   if(Serial.available() >0)
   {
     incoming_char    = Serial.read();
     Serial1.print(incoming_char);
   }  
 }

(I’m using cutecom compiled for Mac OS X)

Baud Rate: 9600
