No response for AT commands

Hi

I am using EG 21 G Mini Pcie Model.

I have connected the Rx Tx Gnd to my TTL adapter.
I am trying to send AT commands to the Module but there is no response seen.

Pls help ASAP

did you cross the lines?

hi, Karthik_H:
You will need to fly out Tx, Rx and GND and connect the TTL adapter, Tx\Rx cross.
