Hi,

I am a new to C++ and am getting link errors when i used the following code. What header file am i missing to include? Thanks in advance.

//************************
//Code starts here
//************************

RCommServ commServer;
RComm comm;

TRequestStatus status;

User::LeaveIfError(commServer.Connect());

_LIT(KCsyName, "dataport");

User::LeaveIfError(commServer.LoadCommModule(KCsyName));

TBufC<12> port(_L("DATAPORT::0"));

TInt ret = comm.Open(commServer,port,ECommShared);

_LIT8(KUSSDString,"AT+CUSD=1,\"*12345#\"\r\n");

comm.Write(status,KUSSDString);
User::WaitForRequest(status);
User::LeaveIfError(status.Int());
User::After(10000);

comm.Close();
commServer.Close();
