Hi Hamed

This article was written in 2007 and it is possible the author is no longer monitoring it. I suggest you raise this query on the Symbian C++ Discussion board.

That said, I don't think it does receive the result.

My dim recollection is that even if you receive the result, there is a default handler in the system that will also receive the result and display the message, an there is no way around that.

Regards

This article explains how to send USSD commands using AT commands.

Introduction

How to dial a string (with pause characters) explains how to Dial a string in S60 3rd edition using CPhCltDialer and TPhCltExtPhoneDialData. This does not work on S60 3rd edition Feature Pack 1.

This article shows how to workaround this problem. The solution is to send USSD commands using AT commands (APIs used are RCommServ and RComm).

Code

Header Files:

C32COMM.H

Libraries:

c32.lib

Capabilities:

CommDD ReadDeviceData WriteDeviceData NetworkControl SwEvent NetworkServices LocalServices

ReadUserData WriteUserData UserEnvironment

code Examples

Initializing code

_LIT(KCsyName,"DATAPORT");
_LIT(KDataPort,"DATAPORT::1");// this works with CUSD
//Start the service to the RCommServ
User::LeaveIfError(StartC32());
RCommServ iCommServer;
// Connect the server
User::LeaveIfError(iCommServer.Connect());
// Load the CSY module
User::LeaveIfError(iCommServer.LoadCommModule(KCsyName()));
RComm iComm;
// Open the port
User::LeaveIfError(iComm.Open (iCommServer, KDataPort, ECommShared));

Issue Request Code

Sending Ordinary Message

_LIT(KTestCommandEnd,"\r\n");
//iSendString has the data which is entered through a Dialog Box
//It should be appended with KTestCommandEnd
iSendString.Append(KTestCommandEnd);
iReplyData.Copy(iSendString);
//We write this information to the serial port
iComm.Write(iStatus,iReplyData);
SetActive();

Handling code after the Request is done

_//Reset the Buffer to read more information
iReplyData.Zero();
//Issue Request for more Information
iComm.ReadOneOrMore(iStatus, iReplyData);
SetActive();

Releasing code

iComm.Close();
iCommServer.Close();

The following is the document which describes how to pass AT commands for Call Waiting and Forwarding:
