Abstract

Système de transmission dans lequel, grâce à l'emploi de modems susceptibles d'effectuer des transmissions de signaux vocaux, les mêmes logiciels sont exécutés par des ordinateurs reliés par l'intermédiaire d'un circuit téléphonique. Tandis que la transmission de signaux vocaux s'effectue, des données, notamment les données de sortie de dispositifs de saisie tels qu'un clavier et une commande par souris, peuvent être transmises simultanément. Le terminal de l'un ou l'autre côté peut être utilisé par l'autre côté pour exécuter le même traitement. Est également décrit un procédé permettant d'utiliser ce système de transmission avec des logiciels classiques sans les modifier.
