communication between xbees

i have two xbee series 1 units(XB24-aci-001) and first i wanted to try and communicate between them, so i connected one to one pc using xbee explorer usb and the other to my laptop using rs232 interface, using hyper terminal, i tried typing at 1 terminal to see if it will receive at the other… but gets no output… am i doin it wrong somewhere for this simple test?

any 1 can shed any light pls!

Did you set the addresses for the two modules? (MY, DL)?
