hi,
i have purchased one gsm module with sim 900A, power supply section, uart, antenna, sim card holder etc.

**broken link removed**
when i connect power supply to module, my newtwork led is blinking. and i can make a call to this number.that means sim 900a is working. but when i connect it to PC via hyperterminal, there is no response. even i can not type on hyperterminal.
in board, level converter section is ok. when i connect sim 300 to hyperterminal of PC via level converter, it is working. but when i connect sim 900, nothing is displayed on PC.
then how can i test that module? nothing is displayed on hyperterminal.
