Hi Gerd,
I think you mostly worked on this:
How to specify -serial mon:stdio using the new syntax? I just ran into
the problem having to define a serial port via -device isa-serial but
wanting its terminal multiplexed with a monitor. -chardev mon:stdio is
not understood.
BTW, there is are thousand ways of shooting yourself into the foot (up
to crashing qemu) by accidentally combining old and new-style options. I
think we should catch and forbid any mixture instead of generating error
messages like this:
qemu-system-x86_64 -mon monitor -chardev stdio,id=monitor -monitor vc
tried to create id "monitor" twice for "chardev"
parse error: vc

-chardev stdio,id=x,mux=on
-device isa-serial,chardev=x
-mon chardev=x
Isn't limited to serial+monitor btw, you can mux everything with up to
four users.
HTH,
Gerd

Almost perfect. I missed it as I was too lazy to look into the sources
(aka: documentation missing :) ). And it starts the monitor enabled
which should be fixed to keep it off until CTRL-A-C just like it used to
be with "mon:".
