Ctrl-A b is simply ignored. Other Ctrl-A sequences seem to work correctly. This is on a NetBSD amd64 system, version 7.99.53, and qemu was installed on this system from source. Reverting to the previous install restores "break" capability. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1654137/+subscriptions
