What exactly are you trying to do?
Trying to read from the tty is prone to failure, because whatever
process you are running will also be reading from the tty, so you'll
just end up with the input being randomly distributed between multiple
processes.
If you stop one of the processes from reading, e.g. by running `sleep 10000'
in one of the shells, then another program reading from the same tty
(e.g. `cat /dev/ttype') will get all of the input.
