You can redirect both input and output for child processes using coproc. However, it does not work for a Bash terminal, because the input and output are internal to the terminal.

You could have output from the second terminal redirect to a file (I suggest a RAM file; create a temporary file in /run/shm using mktemp), and have the first terminal watch for changes to the file using tail --follow or inotifywait.
