The result of the discussion upstream is that the power-up command should only be sent to Sierra Wireless modems if not already in full functionality mode. Basically: if AT+CFUN? already replies AT+CFUN: 1, then skip the power-up command.
Implemented this already in the 'power-up-check-needed' branch in the following git repo: git://gitorious.org/lanedo/modemmanager.git Already tested it with Wavecom modems, which are also affected by the issue. Tests with Sierra Wireless models are highly appreciated. -- 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/ubuntu/+source/modemmanager/+bug/459052/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
