from what i understood the underlying issue is that modemmanager does not serialize disconnects (and probably other operations that modify the baud rate of the tty). This sounds easy to fix by dropping (or queuing) incoming disconnect requests if there is another operation running. Not sure what dan thinks about this approach though ;). - Alexander -- Modem Manager setting bad baud rate, breaking pppd connections. https://bugs.launchpad.net/bugs/414604 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
