B.1.4.4 Driver Mode Configuration
By default, the Wireless WAN driver is enabled (the Enable driver checkbox is checked).
The driver must be disabled in order to use the modem for anything other than GPRS (e.g.
dial-up data, fax, or in order to manually submit AT commands to the modem for develop-
ment, testing, approvals, etc.). If the Enable driver checkbox is not checked, the driver is
shut down as soon as the OK button in the Driver Mode dialog box is chosen.
If, on the other hand, the Wireless WAN driver is not running and the Enable driver check-
box is checked, the Wireless WAN driver is started as soon the Driver Mode dialog box is

network that is not covered by a roaming agreement, the status in the main WWAN
dialog box changes to ‘Emergency calls only’, ‘No network found’, ‘GPRS not
available’ or ‘GPRS not allowed’.
Note: When the driver is not running, no network status or signal strength can
be displayed.
