AT Hangup Command

Okay... so I think I figured out my problem.... before the two modems have completed the connection process, the RCall::HangUp() function does not appear to work on the 6600... but I can sent a direct AT command (ATH) and hangup the call.  After the modems have connected completely, the AT command does not work...as it is looked at as data and sent over the line...but the RCall::HangUp() function WILL work at this point, so.. here is the code that does work.... for both situations...

   // if we are connecting....   
   if( iConxState == EConnecting )
   {
      // put modem in command mode and hangup
      #ifndef __WINS__
         TRequestStatus status;
         iComPort.Write(status, KP2pmModemCommandState);
         User::WaitForRequest(status);
         User::After(KP2pmWaitTime);
         
         iComPort.Write(status, KP2pmModemReset);
         User::WaitForRequest(status);
         User::After(KP2pmWaitTime);

         iComPort.Write(status, KP2pmModemHangup);
         User::WaitForRequest(status);
      #else
         iConxState=EIdle;
         WaitForConnection();
      #endif

      __LOGMSG(_L("CEng::Disconnect(EConnecting)"))
   }
   else
   {
      // in the connected state....this will disconnect the
      // call and hangup the line... we are put in an idle state
      // after this returns....
      iCallManager->Cancel(); //... this calls iCall->HangUp() in the
                                             // do cancel function of the call manager
                                                       // active object.
      // so now lets go back to waiting for a connection
      iConxState=EIdle;
      WaitForConnection();
   }
