Abstract

Système et procédé de communications de données permettant d'envoyer un flux de données de caractères dans des paquets de données distincts entre deux unités d'équipement terminal de traitement de données connectées par des lignes de communications. Un modem est connecté entre chaque unité d'équipement terminal de traitement de données et les lignes de communications, et un modem d'initialisation comprend un moyen permettant de changer la taille des paquets de données, transmis. Selon la réponse du modem de réception déterminant si des erreurs sont détectées, on ajuste dynamiquement la taille des paquets de données. Si l'on détecte une erreur, on diminue la taille du paquet de données, et si l'on ne détecte pas d'erreur, on augmente la taille du paquet de données. S'il n'y a aucun paquet de données à envoyer, on envoie un paquet vide. Si le paquet vide est reçu sans erreur, alors on augmente la taille des paquets de données. Toutefois, s'il y a une erreur dans le paquet vide reçu, alors on diminue la taille du paquet de données.
