Are both processes Ruby processes? In that case it's certainly a lot
more hassle free to use DRb.  If not, you should define a protocol
yourself.  Either use messages with a fixed length or transmit the
length as first item or use a special EOM marker (you could use a line
delimiter for this, which has the advantage that you can use gets or
each without arguments).

Kind regards
