Abstract: In a method of monitoring the reliability of a data link for a data transmission between a server ( 2 ) and a client ( 8 ), a control unit ( 14 ) is triggered by a trigger signal in such a manner that in response to the arrival of the trigger signal the control unit ( 14 ) generates first control data for a predetermined running time which commences anew in response to each trigger signal received. The first control data forms a first control representation ( 23 ) on a client display screen ( 11 ), which first control representation optically indicates the existence of a reliable data link ( 4 ) to a user. The control unit ( 14 ) generates, after expiration of the running time, second control data which generates a second control representation ( 23 ') on the client display screen ( 11 ) which optically indicates the absence of a reliable data link to the user. A control unit ( 15 ) periodically transmits a test message to a test unit ( 18 ). The test unit ( 18 ) returns the incoming test message or another test message to the server ( 2 ). The control unit ( 14 ) is triggered again only if the returned test message is in order. The period with which the control unit ( 15 ) repeats the transmission of the test messages is shorter than the running time during which the control unit ( 14 ) generates the first control data.
