Could you please confirm you indeed have modemmanager 0.5-0ubuntu1? Also, it might be good to look into whether your device needs a firmware update, or whether it really is supported by the changes implemented. There are so many devices, they're all different.
Having the full debug log from the point where that modem was connected will also help, since there may be some extra information about why CFUN=1 doesn't work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/459052 Title: some sierra modem tty's get killed by CFUN=1 To manage notifications about this bug go to: https://bugs.launchpad.net/modemmanager/+bug/459052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
