Avaliable AT commands (Baud 9600,8 Data bits, None Parity,1 Stop Bit): You can test the uploaded code using some free serial software such as Termite (select: Append CR):
AT - attention command (return OK)
ATI - code info
VA - reading status of all inputs
V0x - reading status of single input x (x=1-8 0-1023)
