Follow-up Comment #22, patch #7559 (project avrdude):

There are level shifter ICs... as you know very well. And e.g. the MAX232
doesn't translate more than RX/TX.

But maybe we should forget about RS-232. Nobody with a sane mind uses that
anymore (industrial stuff excluded for now).

And whoever thought that using a negative voltage for logic 1 is a good thing
should not come anywhere near me.
