Problem Discovery Tool to launch GPS


I’m having difficulties running the AirprimeXM0110 GPS module daughter board.
The GSM card works properly.I have connected the GPS module, however instead of using the UART connection I have been using the USB connection. The discovery tool recognizes it.
I then launched the hyperterminal, when I enter the command to start the GPS, I get the following error :

error : +wopen 7,12

Does any of you knows where it may come from ?



thanks it helps me so much !!
