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
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 GSM modems are automatically detected, the Enable auto-
matic 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.
Modem Information
The fields in this dialog box cannot be edited, they only display information about the com-
puter’s modem. If the network operator has not programmed a user’s phone number into his
SIM, the
Phone: field remains empty. If the main menu shows an error status, at least partial
modem information may be available.
