expect is often used for this, by continually reading an IO stream until triggering a particular pattern. You just need to `require 'expect'` and then it will become an instance method of IO, and thus be available to  pipes, network sockets, etc. 

http://www.ruby-doc.org/stdlib/libdoc/pty/rdoc/IO.html

has the documentation on it.
