Abstract
A method is disclosed for transmission of commands or command combinations via a communication link by coded frequency-shift keying. Each command or command combination is associated with one frequency pair. When a command changes from a preceding command or command combination to a subsequent command or command combination, one frequency (which will be the first to be transmitted) in the frequency pair of the subsequent command or command combination is chosen as a function of at least one other associated frequency pair.
