Serial Comms Overview

Provides a framework for serial communications services.

Serial Comms uses the Symbian OS client/server framework. Clients use R classes that send requests to the Serial Comms server. The server in turn passes requests to an appropriate plug-in module that handles the particular communication protocol. These plug-in modules, known as CSY modules, are loaded by the Serial Comms server, and are not directly accessed by client applications.

A Symbian OS phone may include a number of CSY modules as standard, such as for handling RS232 and infra-red serial communications. The Serial Protocol Module API allows new CSY modules to be developed.

Functionality is provided by a number of APIs. Use them as follows:
