    16 on Symbian platform. The information stored in the Comms Database

    17 is used to configure components in the comms stack. Information such as connection

    18 preferences, account settings and some of the linkage between components can

    19 be set in the comms stack. The configuration data is stored in records in

    20 database tables. The data also has data schema to define the tables. For more

    21 information and a full list of the settings in the Comms Database, see the <xref href="GUID-58089281-9DD0-502D-8DFD-831E7BAA931E.dita">Reference</xref></p><p>The
