I have similar problems too. Can you please add ipxe command, which can
disable serial console at menu run? If this happens, I still can put some
keys from serial or bios console, which can run an predefined command
and disable this "feature".

Because I don't know, how this PC is configured, it's hard to have 2
different compiled versions of ipxe and I need a version, which can
disable serial console on run time.

Colours and arrow keys does not work for me too (qemu+ipxe serial).
I don't need colours, it's displayed nicely as serial, what is OK for me.
But arrow keys would be nice. I use menu's hot keys to navigate against
menu, but having other navigation keys keys will be useful.
