A first communication subscriber transmits a first data packet comprising data and an identification character to the second communication subscriber. The first communication subscriber and the second communication subscriber respectively determine a first and a second acknowledgement character on the basis of the identification character. The second communication subscriber transmits a second data packet comprising the second acknowledgement character back to the first communication subscriber. The first communication subscriber can thus check, on the basis of the second acknowledgement character, whether the first data packet arrived at the second communication subscriber.
