Interface DataCallConnection

All Superinterfaces:

javax.microedition.io.Connection, javax.microedition.io.InputConnection, javax.microedition.io.OutputConnection, javax.microedition.io.StreamConnection

public interface DataCallConnection
extends javax.microedition.io.StreamConnection

This interface defines the GSM Network data call stream connection. This connection is defined as a logical connection through which bytes are transferred serially over a circuit switched air interface.

DataCallConnection Usage

To transfer data over a DataCallConnection, first establish a data call (incoming or outgoing) as described in Call. Once a data call is connected, you may open a connection as follows:
d_call = (DataCallConnection) Connector.open("csd://",Connector.READ_WRITE,true);
To Access the already opened DataCallConnection, use: Call.getDataCallconn().
Once a reference to this implemented interface is available, use standard StreamConnection methods to read and write data as well as to control the connection.

A DataCallConnection object can only reference a single GSM data call at a time, and there can only be one DataCallConnection at a given time.

DataCallConnection instance has one underlying InputStream and one OutputStream. A DataCallConnection instance can have only one InputStream and one OutputStream open at a time. Trying to open more than one InputStream or more than one OutputStream from a StreamConnection causes an IOException. Trying to open an InputStream or an OutputStream after the DataCallConnection has been closed causes an IOException.
