Sending AT commands and DTMF during an active call in UIQ

First I set up a phonecall programatically
Code: RCall call; call.Dial(number); then I loan this calls dataport Code: TRequestStatus stat; call.LoanDataPort(stat, dataport); User::WaitForRequest(stat); and then open the dataport Code: RCommServ server; RComm comm; comm.Open(server, dataport.iPort, ECommShared); finally writing to the port Code: _LIT8(KATCmd, "AT+VTS = ? \n"); comm.Write(stat, KATCmd); User::WaitForRequest(stat); ViewMessage(stat.Int()); The problem here is that stat.Int() is -29, which is KErrCommsLineFail Solutions?

RComm comm;
commServer.Connect();
_LIT(KCsyName, "ECMUX");
User::LeaveIfError(commServer.LoadCommModule(KCsyName));
TBufC<12> port(_L("MUXCOMM::1"));
comm.Open(commServer, port, ECommShared);
TRequestStatus stat;
_LIT8(buf8, "AT+VTS=1,2,3\r\n");
comm.Write(stat, buf8);
User::WaitForRequest(stat);
comm.Close();
commServer.Close();
This should genereate the DTMFsounds according to pressing the buttons 1,2,3. (in that order)

Hi,
I have one question.
How is exactly the datacall established??
From where the connection starts and exactly do the AT COMMANDS go thru ETEL for the connection ??

Hi,
This is not a datacall. Only after an ordinary call is ongoing, this part of the code is executed.
The DTMF tones is just "played" over an already ongoing call.
