Abstract

La présente invention concerne un procédé et un système pour émuler une communication par port série. Un système de traitement informatique présente des instructions de système d'exploitation exécutables sur ordinateur comprenant des premières instructions qui interagissent avec un premier dispositif sériel, selon une interface matérielle d'entrée/sortie (I/O) prédéfinie. Un premier dispositif sériel présente un port de réception et un port d'émission et comprend ladite interface matérielle (I/O) prédéfinie. Un second dispositif sériel présente un port de réception et un port d'émission. Le port d'émission du premier dispositif sériel est en communication série avec le port de réception du second dispositif sériel et le port de réception du premier dispositif sériel est en communication série avec le port d'émission du second dispositif sériel. Des instructions exécutables sur ordinateur émulent une communication de dispositif à port de communication série et comprennent des instructions qui transmettent des informations sur un autre support, en réponse à la réception de requêtes provenant du second dispositif sériel. Les informations transmises comprennent des informations représentant la requête de réception provenant du second dispositif. Des transmissions vers le premier dispositif sériel par les instructions de système d'exploitation sont effectuées sur l'autre support et une communication de dispositif à port de communication série est ainsi émulée sur l'autre support. Les instructions d'émulation comprennent également des instructions qui, en réponse à une communication reçue provenant de l'autre support, transmettent des informations représentant la communication reçue vers le port d'émission du second dispositif sériel. Le système d'émulation communique avec au moins un dispositif de console. L'autre support comprend un réseau à commutation par paquets. L'autre support comprend un réseau cellulaire. Le système d'exploitation communique directement et uniquement avec ladite interface matérielle (I/O) prédéfinie.
