Abstract

Un dispositif électronique comprenant une interface de communication, une mémoire, et un processeur est divulgué. Le dispositif électronique peut être configuré pour : mettre en œuvre une communication sans fil au moyen d'un dispositif de modem connecté par l'intermédiaire de l'interface de communication ; déterminer s'il faut recevoir des informations de journal comprenant des informations d'événement du dispositif de modem sur la base d'un état de fonctionnement du dispositif électronique ou d'un état de communication du dispositif de modem ; lorsque la réception des informations de journal est déterminée, recevoir les informations de journal provenant du dispositif de modem ; et stocker les informations de journal reçues dans la mémoire. Divers autres modes de réalisation identifiés tout au long du présent document sont possibles.
