From what I understood (I might be wrong) while the pbforth kernel is running the buttons have no predefined action, so there's no way to make the RCX sleep without using the terminal console.

I have created a new site as a reference for educators using RoboLab in the classroom. I would love to have some of you visit the site and provide feedback. At present we have only a few examples, but we are working on adding many more. The most (...)
