Hi,

Answer 1:
The Ctrl-Alt-1 window displays LCD/VGA output.
For the PC, Mips and Powerpc emulations, it also
accepts keyboard input (for others, it should, but
I did not test this). It depends on qemu for maemo
and on the guest operating system whether
keyboard input will work in your special case.

Answer 2:
The default number of serial consoles is usually
one, but there are also emulated machines with
more than one serial console in their default setup.
Most machines accept two serial consoles.
There was a problem with interrupt conflicts which
did not allow two consoles on arm based machines,
but this is solved now. More than two serial consoles
are possible, too, but that increases the chance of
resource conflicts.
