And further, the S720 is one of those cards that uses proprietary protocols to deliver signal strength on the additional tty devices. So unless somebody figures out the protocol, or Novatel opens up the protocol, you'll never be able to get signal strength out of the card under Linux. Recent Sierra cards, some Huwei, and most Option cards are able to deliver signal strength using normal AT commands, which we'll support soon in NetworkManager. But for most old Sierra cards and most Novatel cards, you are simply SOL. Dan -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
