Yeah, I didn't notice you are running QEMU on Windows. I guess serial port
is not redirectable under Windows and there are no current plans to.

Under Linux I use -serial to redirect to a pty. Then you can use other apps
or emulators that will talk to a pty device. The most interesting
application here is probably socat or netcat since these will let you shunt
the serial channel onto pretty much any kind of two-way channel (for example
you could connect the pty to a real serial port, or a TCP connection to an
instance of socat on another machine, etc.)

For anyone who hasn't played with socat it's really an amazing tool.
