Redirect stdin -> tty, tty -> stdout

| Hi,
I wrote a simple program that does the following:
Thread 1: c = read(stdin); write(tty, c);
Thread 2: c = read(tty); write(stdout, c);
Basically, send everything from stdin to the tty, and send everything
from the tty to stdout.
This is so simple it must already exist, hopefully with all the gory
tty details handled nicely. Do you know any such program?
Thanks,
Daniel

I have trouble seeing where this would be useful. Reinventing /usr/bin/script?

This makes a simple serial terminal in Emacs.
