Sorry, I think if you examine which letters are incorrectly cased you will
find a correspondence with the parity bit.  The shift keys do not occupy
positions in the key matrix that would cause this sort of problem, even with
the worst keyscan code AND the longest, noisiest cable imaginable.  You may
not be connected to a host, but are you still connected to your modem?

>How did we get into a user port discussion, by the way????

I'm assuming you're interfacing to rs232 via the user port (aka parallel
port).  I explained one connection between SID and rs232 was the 9VAC
supply.  The only other connection is through the 4066 analog switch to
the key lines, but a problem there would not affect strictly the case of
certain letters (as evidenced by occasional problems reported when a mouse
or joystick is also wiggling the key lines).

Enough.  Perhaps Kermit should simply mask bit 8 if it's in 7 bit mode.
