Sorry, not correct... a stop bit is simply the line sitting in the
spacing state, eg. it's like a pause between characters, so it
will not trip up comm. systems.
It's always safe to have more than one stop bit, though it lowers
the number of characters/second (at 110, you'll hardly notice :-)
I'm a little unclear on your problem, I'll restate for clarity,
correct me if I'm wrong:
** When you type on the tty keyboard, correct characters appear on
the laptop? Absolutely 100% of the time?
** When you run a punched paper tape through the reader, it prints
correctly on the tty, but what you see on the laptop does not
match the tty?
