Claim 0:
1. A user station for a serial bus system having user stations, comprising:
a communication control unit configured to create a message which is to be transmitted serially to a first at least one further user station of the bus system, or to read a message which has been received serially from a second at least one further user station of the bus system; and
a transceiver device configured to transmit the created message on a bus line to the first at least one further user station of the bus system or to receive a message from the bus line;
wherein the communication control unit and/or the transceiver device is configured to provide, in the created message to be transmitted, an ACK time window for an ACK signal and/or a NACK time window for a NACK signal for a signaling of whether or not the first at least one further user station has identified an error in the transmitted message, and the transceiver device is configured not to drive any level on bus line in the at least one provided time window during the transmission to the first at least one further user station, such that a recessive bus level arises with a value between a first bus level value and a second bus level value.
