Not exactly, for some reason, the win-chr-pipe uses a poll, win_chr_poll()
that read from the pipe and write to the frontend (the vm serial).  I
haven't tested the windows pipe implementation, only the console one, but
it looks like it should work. Hopefully someone using qemu on windows can
help you.
