Is it still possible to use a modem that was supported in a previous i.LON release and that was deleted from the SmartServer 2.0 release?
Yes, you can copy the entry for the modem from the connectionManager.XML file on your i.LON running the earlier release to the connectionManager.XML file on your SmartServer 2.0. Reboot your SmartServer after changing the file. Any changes that you make to this file may be overwritten by future updates or upgrades.
