Abstract
A method for controlling data transmission in a cordless V.24 data transmission system operated between a data terminal and data communication equipment. The method controls data communication equipment for the purpose of data communication with a first data transmission device connected to the data terminal equipment via a V.24 cable and with a second data transmission device connected to the data communication equipment via a V.24 cable. The first and second data transmission devices can be connected via an air interface by wireless telecommunication. Activating, reactivating and deactivating of an auto-bauding function is reliably performed in such a manner that there is no risk that user data transmission is corrupted until it is deactivated. A state machine contained in the first data transmission device tracks the states of the data communication equipment and acts on the state of the auto-bauding function in the first data transmission device. In the alternative, a state machine contained in the second data transmission device tracks the states of the data communication equipment and acts on the state of the auto-bauding function in the first data transmission device.
