6.33.5.4 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 access the modem directly (e.g.
dial-up data, fax, or in order to manually submit AT commands to the modem for
development, testing, approvals, etc.). In most cases, the Virtual WWAN serial port
can be used and it is not necessary to disable the WWAN driver. 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 tapped.
If, on the other hand, the Wireless WAN driver is not running and the Enable driver
checkbox is checked, the Wireless WAN driver is started as soon the Driver Mode
dialog box is closed using the OK button.
Note: When the driver is not running, no network status or signal strength can
be displayed.
Since all currently supported modems are automatically detected, the Enable
automatic port detection checkbox should always be checked. If this checkbox is
not checked, a serial port can be selected manually. This experimental feature allows
the driver to be used with an internal GSM modem that was not recognized by the
automatic detection or an external GSM modem connected to a serial port of the
computer through USB or through Bluetooth. An external modem connected to a
serial port must support 115.2kbit/s, 8bit, no parity and hardware flow control.
