Chapter 8: Managing a Mobile Device Server 69Server Authentication Forces mobile devices to communicate with a single known server.Mobile devices must first connect to the network through a serialconnection (RS232) to receive information about the server withwhich they are allowed to communicate. When you enable thisoption, the mobile device will challenge any Mobile Device Serverattempting contact for a password. If the Mobile Device Server doesnot have the correct password, the mobile device will not allow aTCP/IP connection.Both authentication options require mobile devices to connect to the network through a serialconnection to receive authentication information before they will be allowed to connectwirelessly. Authentication passwords are set through a dialog box. This dialog box appearswhen the options are first enabled, or you can click Set Password next to the desiredauthentication option.Server ResourcesA Mobile Device Server profile allows you to configure the following aspects of serverresources:ReservedSerialPortsConfigures a Mobile Device Server to automatically listen for mobile devices usingthe serial ports on a remote system. Only one application on a host system canmaintain ownership of a serial port. If the Mobile Device Server controls the serialports on the host system, then no other application will be able to use them.Likewise, if another application on the host system (for example, MicrosoftActiveSync) has control of the serial ports, then the Mobile Device Server will notbe able to use them. If you list more than one port, separate them with semicolons.For example: COM1;COM2Serial connections are required to implement Mobile Device and ServerAuthentication methods.TerminalID RangeThe Mobile Device Server assigns each device a terminal ID the first time that thedevice communicates with the Mobile Device Server. The number the MobileDevice Server selects is the lowest number available in a range of numbers you canconfigure.You also have the option to use a C-style format to create a template for theterminal ID range. For example, Seattle-%d would generate IDs such asSeattle-4, and Seattle-%05d would generate IDs such asSeattle-00004.To change a terminal ID that has already been assigned to a device, click EditTerminal ID on the Properties tab of the Mobile Device Details dialog box.
