You are reading one character at a time, so ICANON is not set and ^D is an
ordinary character. It's on
OK, that makes sense. Sorry for being confused. I thought that by this
level, ^D and EOF are equivalent. I should be able to check to see if
the character returned is ^D, then act accordingly.

It seems it is something like this:
$ read -n3
12^D$ echo $?

Hm, that's a whole other problem then. I can reproduce this by
following that path.
I was using ^D as an EOF. I guess I should have tried it in other ways.
Is ^D not the same as EOF? Sorry if that is a noob question. I was able
to reproduce all of your outputs. I am using xterm as my terminal
emulator, if that matters.
