AT Command ^U2DIAG values to activate/deactivate features on the Huawei E173 USB Modem (other modems are similar, but you must try one by one):

NDIS = Network Card
DIAG = 3G Application Interface
PCUI = PC User Interface
PCSC = Generic smart card (don't know how to use it though)
CDROM = CD image (Mobile Partner and drivers)
