Abstract
A method transmits data packets on a data transmission link between two communication subscribers. The data packets respectively contain a check character which is calculated from the other data in the data packet. One communication subscriber uses the check character from the last data packet received by the other communication subscriber as start value for calculating the check character for a subsequent data packet which is to be sent to the other communication subscriber.
