                  This method is meant for standard requests where the size
                  of the reply is known in advance. Therefor no dynamic memory
                  is needed to process the reply (e.g. COM_CANCEL)
                  Sollte geändert werden, dann können z.B. auch die AWE requests
                  behandelt werden. Der Aufrufer muss dann immer für einen ausreichend
                  gross dimensionierten Speicher sorgen. Aber dass wollte ich clientseitig
