Input from another tty

[David D. Dean]

Hello :-)

        I was wondering if there was a special command that I had to use 
to have a program of mine - when I run it - accept input from another 
terminal?  I have tried many times with different forms of:

        read ANW < /dev/dk???
      
        while (true) do
        cat (filename)
        done&
        (then have the other terminal write to (filename)


I think that what I'll have to do, is to setup a  sub-routine to always 
check a set file for new input and then grep the info in that file.

If anyone can understand this mad reasoning.... any input would be 
appreciated!

Thanks!
