5I've now tried removing the atmega328 from the arduino socket, powering up the 
board by momentarily touching 3.3v to pin 8. The led flashes.

Then I ensure my terminal is 8 data bits, no parity, one stop bit, 9600 baud.

I wait for 20 seconds then send

AT\r (carriage return)

And get nothing back.

ok, forgot to switch pins rx and tx when removal of the atmega. So now have an 
OK after AT.

ok, forced the sim900 to 4800 baud and now the demo program works. So for some 
reason the autobauding doesn't work or had changed on this module.

Hi all.
(1) Hardware:
I'm using TiDiGino
http://www.futurashop.it/allegato/7100-FT924M.asp?L2=CONTROLLI%20REMOTI%20GSM&L1
=MODULI%20GSM%20E%20SISTEMI%20GPS&L3=&cd=7100-FT924M&nVt=&d=138,00
received a week ago.

(2) Software:
BETA_GSM_GPRS_GPS_IDE100_v305.zip

using sketch GSM_GPRSLibrary_SMS.ino

and have the same identical problem 
Reported by matthewv...@gmail.com, Apr 25, 2013

  //Serial connection.
  Serial.begin(9600);
  Serial.println("GSM Shield testing.");

  if (gsm.begin(2400)){
     ...

I never reach READY status.

PS where can I found DebugPrint to avoid a series of errors like:
D:\Arduino\arduino-1.5.2\libraries\GSMSHIELD/GSM.cpp:573: undefined reference 
to `GSM::DebugPrint(char const*, unsigned char)'
and understand where is the problem on Hardware or on Software?

TiDiGino is not supported yet.
We're going to make this lib compatible with it soon! :)
You can find the debug on GSM.cpp on the first lines.
You should remove first '//' from //define DEBUG_ON
to have define DEBUG_ON
and re-upload the lib.

This is not a good new for me.

Anyway one more question: where can I found DebugPrint?

I have enabled DEBUG_ON but the message: 
D:\Arduino\arduino-1.5.2\libraries\GSMSHIELD/GSM.cpp:573: undefined reference 
to `GSM::DebugPrint(char const*, unsigned char)'
remains.

Where can I found DebugPrint if is not defined in GSM.cpp? 

Thanks in advance.

Sorry the right file is GSM.h line 20.
Try to redownload the lib and modify only the 20th line of GSM.h
