    I am following the tutorial at this link:

    I am at the step where I am supposed to type ‘AT’ in the window. For some reason, I am not able to type anything – it’s like the keyboard just stops working…except it is. The keyboard works just fine before this step (where I am entering the letters to set up the port) and it works just fine after I close out of the terminal window. It is just at this particular point, after I switch the serial port to ttyUSB2 and exit that they keyboard no longer works. I have even tried typing ‘AT’ with a virtual keyboard (matchbox), but nothing will work.

    Any suggestions on how to resolve this?



    The ATE command controls whether or not the module echoes characters received from TE during AT command mode.

    Type ATE1 to turn on the echo mode.
