Comms Database Configuration Overview


Purpose

Symbian OS maintains a database of communications-related configuration settings. This database is called the Comms database, and is always available on any Symbian platform. The Comms database is accessed and manipulated by various tools and applications that need to manage voice or data transmissions using any kind of network technology. The Comms database contains the necessary configuration data for managing any kind of data connection on any kind of network.

For example, to configure a modem, you need to set fields such as:

Name=Default Modem
PortName=COMM::0
DataBits=8
StopBits=1
Parity=NONE
Rate=115200

You can manage the database statically using the command-line tools CED and CEDDUMP, or dynamically using the COMMSDAT API.

For information about the mechanics of configuring the Comms database using the CED and CEDDUMP tools, see Configuring Comms database using CED and CEDDUMP

For information on the file formats supported by CED and CEDDUMP, see Comms database configuration file format

For reference documentation on all the fields of all the public tables in the Comms database, see Comms Database Reference in the CommsDat engineering documentation.

For reference documentation about the APIs that manage the Comms database, see Comms infras COMMSDAT
