HI,
I have bought a SIM900 modem. When I insert a sim card in it & call from another mobile number the ring detect led on it glows i.e the modem connects with the network, but when I connect the modem with hyperterminal using a cross cable ,( the modem does not connect using straight cable),if I try to test it with AT + enter, I get some weired garbage values like (* !) , I am just not able to diagnose the problem Please suggest any solution.
