$ qemu-system-x86_64 -chardev null,id=chr0,mux=on -mon chardev=chr0 -mon chardev=chr0 -mon chardev=chr0 -mon chardev=chr0 -mon chardev=chr0
and

fail with
qemu-system-x86_64: -mon chardev=chr0: Device 'chr0' is in use
Improve to
qemu-system-x86_64: -mon chardev=chr0: too many uses of multiplexed chardev 'chr0' (maximum is 4)
and
qemu-system-x86_64: -mon chardev=chr0: chardev 'chr0' is already in use
