May be something weird in your /etc/ttys?  Like getty on both cons*
and ttyE0 and the like?

The input either works and just not echo'ed and needs explicit ^J
instead or <enter> to get read by the program.  Or it may be stolen by
the other program reading from the terminal.

Switch to another console and check "ps auxww" output for processes
that use ttyE0.

readline explicitly manipulates tty state, so it can dodge a lot of
weird terminal conditions.
