Services

A Uniform Resource Identifier (URI) is a string that identifies a particular location in a file system or on the Web. For example, the web address of a web page is a URI. A service is a protocol or task that a URI requests. For example, the http://www.gnome.org URI requests the http service.

You can associate an application with a service, so that the application performs the task required by the service. For example, you can associate your preferred web browser with the http service.

Configuring PDA Devices on Linux Systems

To access the PDA Devices preference tool, click Launch, then choose Preferences -> Desktop Preferences -> PDA Devices.

A personal digital assistant (PDA) is a hand-held computer that you can use as a personal organizer. You can store appointments, tasks, contacts, and other information on your PDA. You can also transfer this information between your PDA and applications in the Java Desktop System on Linux. For example, you can copy your calendar appointments from your PDA to Email and Calendar, and from Email and Calendar to your PDA.

When you transfer data between your PDA and your computer, you perform a HotSync operation. The actions that occur during a HotSync operation are controlled by conduits. A conduit is an application that manages the transfer of data between your computer and your PDA.

One of the actions that you can specify for a conduit is to merge data between your PDA and your computer. This is called a synchronize action. For example, you might add contact information to your PDA, then add different contact information in Email and Calendar. You want to add the contact information on your PDA to Email and Calendar, and you want to add the contact information in Email and Calendar to your PDA. To do this, you must synchronize the data between your PDA and Email and Calendar.

The PDA Devices preference tool enables you to configure a PDA to work with the Java Desktop System on Linux, and to modify PDAs that you have already configured. You can perform the following tasks with the PDA Devices preference tool:

A background application waits for a PDA to attempt to synchronize with your computer. This background application is called the PDA daemon. When a PDA attempts to synchronize with the computer, the PDA daemon synchronizes the data on the PDA with data on the computer.


Tip –

The PDA Monitor panel application displays the activity of the PDA daemon. To add PDA Monitor to a panel, right-click on the panel, then choose Add to Panel -> Utility -> PDA Monitor. For more information about PDA Monitor, see the online Help for PDA Monitor.


To Configure a PDA

You can configure a PDA in one of the following ways:

To Use an Assistant

Perform the following steps:

  1. Connect your PDA to your computer. If your PDA has a cradle, place the PDA in the cradle.

  2. Click Launch, then choose Preferences -> Desktop Preferences -> PDA Devices to start the PDA Devices preference tool. Click on the Forward button in the assistant to begin the configuration process.

  3. Enter information about how the PDA connects to your computer in the Cradle Settings page. The following table describes the settings in the Cradle Settings page:

    Element 

    Description 

    Name

    Type a name for the connection in the text box.  

    Port

    Enter a port for the connection in the drop-down combination box. For example, if your PDA uses a Universal Serial Bus (USB) port, you might enter /dev/ttyUSB1 in this field. If the PDA does not connect properly, you might need to try another port.

    The default value for the Port field is /dev/pilot. If you do not want to change the default value in this field, you can make a symbolic link from the port that the PDA uses to /dev/pilot. For example, if your PDA uses a USB port, run a command similar to the following command:

    # ln -s /dev/ttyUSB1 /dev/pilot


    Note –

    You must have the appropriate permissions to access the port that you specify. If you do not have the appropriate permissions, contact your system administrator.


    Speed

    Select the speed of the connection from the drop-down list. 


    Tip –

    Select the lowest speed. When you are sure that the connection to the PDA works reliably at the lowest speed, select the next highest speed. Continue to do this until you find the highest speed at which the connection to the PDA works reliably.


    Timeout

    Use the spin box to specify the number of minutes for the connection to be idle before the connection is broken. 

    Type

    Select the type of port from the following options: 

    • Serial: Select this option for a serial port.

    • USB: Select this option for a USB port.

    • IrDA: Select this option for an infrared port.

    • Network: Select this option for a network connection port.
