Would it be possible to add in support for a serial line?
I wouldn't like emulating another Atari chip so I'd rather add a simple
natfeat driver to the linux kernel, if it is acceptable.
That would work, too. As long as one can interact with the emulator
using, say, perl or expect, that's okay.
Yes, I thought of Xvfb, but that would make the whole setup rather
heavy, so it would be preferable if that wasn't necessary. But if it's
not easy to disable SDL, then that's okay -- we can cope with having to
run Xvfb, I guess.
