So that text should probably start with: On a serial console, one can type the escape character [[....]] From what I see in the Xen code it wouldn't be hard to add PS2 keyboard support to Xen, but these days I suppose there wouldn't be much point. (and adding USB support, even just for a keyboard, would probably require quite a bit more code with quite a few more hardware specific quirks and other such difficulties) -- Greg A.
