Urr? This is not the responsibility of a processor emulator. At
least it isn't on any sane platform.
SIMH (the PDP-11 part of it) spits the characters out to its
controlling terminal as it receives them from the emulated PDP-11's
console (addr 777566) serial port. As all common CLI access programs
(xterm/gnome-terminal/etc under most Unices including OS X, additionally
Terminal.app and iTerm.app under OS X) all speak ANSI by default, you
get the correct behavior even on the console.
And the only PDP-11 OS in which one is essentially *required* to use
the console all the time is RT-11, which is the least-capable of all of
the various PDP-11 OSs anyway, perhaps excluding some very early stuff
like CAPS-11 and DOS-11.
(I'm not knocking either Ersatz-11 or RT-11, because I love 'em both,
but just injecting a little reality here)
