For mobile boradband I need to get some network related infos, localization (LAC+CI) among them. What I understand is that I need to write a D-BUS client to ask the modem manager to gather the infos on my behalf. But for POTS and ISDN modem I just need to make some specific initialization which apperas to be not possible at all. -- Vincenzo Romano at NotOrAnd Information Technologies _______________________________________________ networkmanager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
