This wasn't possible before, and also not possible in this proposal, as there is only one Preferred Mode given here. If we would like to allow giving the order of priority to select the modes, as you suggest, we would need to give a list of mode values instead of just one single value. The key point here is what existing modems currently support. It would be great to allow in the API to specify a given order of modes, but then the modems should support that, and AFAIK no modem supports specifying such order. Some modems may allow to force using only 1G or 2G (e.g the Wavecom I've got, you can force it to setup a slow CS data connection), without any notion of having one 'preferred' mode; some other modems allow specifying "2G preferred" or "3G preferred", as we have in the 0.5 API. This proposal doesn't possibly cover all currently existing cases, but at least I tried to do so. Of course, if any given combination is not supported by the modem, the plugins can always return a GError in the SetAllowedModes() call. For example, modems without any notion of 'preferred' modes could allow only NONE to be set as Preferred mode. -- Aleksander _______________________________________________ networkmanager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
