[SOLVED] Why I couldn't get 'OK' response after I command AT on hyperterminal?

[misswah]

I'm done configuring my XbeeS1 module on X-CTU and I did it successfully. Now, I'm trying to configure it using hyper terminal. I followed this step Xbee Adapter - Connecting, Configuring and Upgrading and can now type on hyper terminal. When I type '+++' I get 'OK' response which is good. However after I type 'AT', there is no more response
pls enlighten me

Instead of normal AT commands, you may need to use a specific command set as designated by the manufacturer of your module.

Their website ought to have the info you need.
