    Abstract: In order to insure the accuracy of information transmitted over a network, the initiation of the message must be unambiguously identified. In the present invention, the intermessage spacing consists of a series of identical logic signals that exceeds a minimum value distinguishing this interval from a message character. The message character has predefined length, with a start bit position and a stop bit position logic signal bounding the character that have the same predetermined logic signals for every message character. The character has at least one additional non-data bit position that has a first logic signal for the initial character of a message and the complementary logic signal for the remaining characters in the message.

    Abstract: Afin d'assurer l'exactitude d'informations transmises par un réseau, le début d'un message doit être identifié sans ambiguïté. Selon l'invention, l'intervalle entre des messages comprend une série de signaux logiques identiques supérieure à une valeur minimale qui permet de distinguer cet intervalle d'un caractère faisant partie d'un message. Les caractères qui font partie de messages ont une longueur prédéfinie, avec des signaux logiques qui caractérisent la position binaire initiale et la position binaire finale, délimitant ainsi le caractère, ces signaux logiques prédéterminés étant les mêmes pour chaque caractère du message. Le caractère comprend au moins une position binaire supplémentaire ne faisant pas partie des données qui contient un premier signal logique comme caractère initial du message et son signal logique complémentaire pour les caractères restants du message.
