I think "plain wrong" is the better answer :)

You are indeed sending to the tty device by shell redirection, but you
are not reading from the tty anywhere. If you really want to do this in
a shell, you could probably set up reading e.g. in another terminal
window or virtual console:

cat </dev/tty.XXX

but I'm not sure if this will work, depends on locking etc.
(You could also set up this in the background with & etc.)

A better idea is to use a terminal emulator such as minicom to talk to
your phone/modem.
