Has anyone done anything with the 3270 protocol in Ruby? I write a lot of code that needs connectivity to IBM mainframe hosts via TN3270E. At the moment, I do that by 'wiring up' a terminal emulator and telling it to do things for me. However, this means that I only get one instance per terminal session, and because these things are graphical, I can't run it headless inside a cron job, etc, etc. I now need something more industrial-strength that I can run many concurrent copies of, etc, etc. I'd like to build a Ruby framework for the kinds of things I do with 3270, and slap it on top of a library. For fellow mainframe geeks, imagine (totally contrived example, probably not what it would look like): host.screen do |s| s.put :text => "Hello World" :field => 'fieldname' s.transmit if scr.ready? end Unfortunately, I can't find anything that implements 3270 other than terminal emulators and other application-level stuff. It would be nice if there were some C library that could be wrapped as a Ruby extension. Has anyone done anything like this, and just kept it around for personal use? I'd like to avoid reinventing the wheel, but if I'm the only one with this need, I'll go ahead and start working on a library. Thanks, --Wilson.

Wilson, I'm currently writing a book on enterprise ruby on rails for addison-wesley and your message definitely caught my eye because it's one of the topics I want to cover. I don't know of any software like you describe, but if you would like to discuss possible collaboration please let me know and we might be able to figure something out. Obie

Cool. I'm going to head out for some serious pumpkin pie consumption in a few minutes, but I'll get in touch, possibly also on IRC. I still hold out hope for some existing work in this area; there's a rumor that someone I failed to meet at RubyConf does this sort of thing at NASA, but I don't have any details. Thanks, --Wilson.
