[Qemu-devel] [Bug 1654137] Re: Ctrl-A b not working in 2.8.0

I am also seeing this problem.  In case it was not clear from Paul's
original report, it affects guests using a serial console.

Also, it is not specific to NetBSD.  I can reproduce it using a Linux
guest on a Linux host, by running the following on a Debian 8 system:

  tar xfz system-image-i686.tar.gz 
  cd system-image-i686
  sh run-emulator.sh 

and typing Control-A b m once the guest has started.

Using qemu 2.1.2, this successfully causes the guest to print a memory
usage summary.  Using current qemu sources from git
(dbe2b65566e76d3c3a0c3358285c0336ac61e757), nothing happens.

  Ctrl-A b not working in 2.8.0

Status in QEMU:

Bug description:
  With a recent update from 2.7.0 to 2.8.0 I have discovered that I can
  no longer send a "break" to the VM.  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.
