MM supports plain RS232 modems (e.g. some Cinterion ones or Iridium satellite modems). In MM 0.6.x we had a blacklist for serial devices which are definitely not modems. In this list we (upstream) didn't include USB<->RS232 adapters, although several distributions then added those in the blacklist when packaging (therefore removing support for RS232 modems connected via USB<->RS232 adapters). To solve this issue and avoid having distros ship additional blacklist rules, in MM 1.x we added an additional 'greylist', so that we have: * a blacklist for serial devices which are definitely not modems (as we had in 0.6.x upstream) * a greylist for USB<->RS232 adapters, as they may have a RS232 modem behind. In this setup, MM will never probe the blacklisted ones, and will only probe the greylisted ones if a manual Scan() is requested (i.e. never automatically). Setups using MM with a RS232 modem will anyway need a periodic explicit Scan() to detect whether there is a modem in the serial port (both with platform ports and for USB<->RS232 adapters), so applying the greylist only for this case is actually appropriate. -- Aleksander _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
