Psion Teklogix 8100107B user manual Use Virtual Serial Port, Enable Automatic Configuration

Chapter 6: Settings

Tools Menu

To activate the automatic connection mode:

•Tap on the OK button.

While automatic connection mode is enabled, the Connect Data button in the main Wireless LAN dialog box changes to Disable Auto.

To close the currently active connection (if any) and disable the automatic connection mode:

•Tap on Disable Auto.

Important: Automatic connection mode should not be used if applications other than the Wireless WAN user interface (e.g. Connection Manager) are expected to open and close connections.

If the automatic connection mode is enabled and another applica- tion closes the packet data connection, the WWAN user interface will immediately try to re-establish the connection.

Use Virtual Serial Port

If Use virtual serial port is enabled, packet data connections are established through the virtual serial port of the WWAN driver rather than through the WWAN driver directly. This checkbox should only be checked if certain third-party VPN (Virtual Private Network) clients are used that do not work correctly otherwise. The default setting is disabled (unchecked).

Note: The connection setup takes longer through the virtual serial port.

Enable Automatic Configuration

In most cases, the data connection is configured automatically and no user interaction is required. This is true even if multiple SIM cards from different operators are used with the same device. The connection parameters are adjusted automatically when a new SIM card is detected (this may require a reset). The connection parameters are retrieved from a database.

Manual configuration should be necessary only if:

•One or more parameters in the database are incorrect or a new operator is not yet in the database. (The database should be corrected for subsequent software releases.)

•An operator has assigned individual packet data user names and passwords.

•A very large site has their own APN. Such connections always have to be configured manually.
