   * The application can send one operation at a time.  It can send a 
   * new operation immediately after sending the previous operation. 
   * Thereby several operations can be active in one transaction within TC. 
   * This is achieved by using the API connect record. 
   * Each active operation is handled by the TC connect record. 
   * As soon as the TC connect record has sent the     
   * request to the LQH it is ready to receive new operations. 
   * The LQH connect record takes care of waiting for an operation to      
   * complete.  
   * When an operation has completed on the LQH connect record, 
   * a new operation can be started on this LQH connect record.
