(...) It's amazing, but I get all kinds of comments on how it's impossible to debug systems like the RCX brick. I guess if you're used to deeply embedded systems, figuring out how to let it tell you what's going on is a big part of the magic... (...) (24 years ago, 15-May-00, to lugnet.robotics.rcx.pbforth)

(...) Actually that's what I was intending but I couldn't remember the words at my keyboard. To make debugging easier I will use parallel words that can be merged in later. I was going to use the following debugging strategy: Put the isr init in a (...) (24 years ago, 15-May-00, to lugnet.robotics.rcx.pbforth)

Ralph, I'm getting tired of losing characters going to the RCX on the serial port because forth is busy. It is making my work more complex than it needs to be. If you are not going to do serial port interrupts I will take a shot at it if you give me (...) (24 years ago, 13-May-00, to lugnet.robotics.rcx.pbforth)

(...) Ummm, great idea. How about an item that turns into a pulldown list of 1-liners? I've got the X close or AltF4 shell closing capture thing, and I've also got XMODEM working. If I can get enough time, a public beta is in order... Cheers, Ralph (...) (24 years ago, 13-May-00, to lugnet.robotics.rcx.pbforth)

Ralph, I suggest that you factor a proceedure out of the tcl uploadScript that sends a string to the RCX. This could then be used for additional menu or tcl commands that send Forth code to the RCX. Here is a potential implementation used to power (...) (24 years ago, 13-May-00, to lugnet.robotics.rcx.pbforth)

I think that's a great idea. I find example code the easiest way for me to learn. The pbForth can be little intimidating at first, (you can't even turn off the power with the on-off button).
