The GUI version is 2.1.0.
The pbForth version (COLD) is 2.1.2.
I am using the USB tower with RIS 2.0.
Once the RCX stops responding, if I pull out a battery and re-upload the
firmware, the RCX will respond again to the same GUI session. In other words,
it doesn't appear to be the GUI that is experiencing the problem. It will
continue to send messages after the RCX has been rebooted.
It seems that it may be due to handling communication errors that the problem
comes up. I can recreate the problem exactly every time by pointing a
flashlight at the RCX. The first time the problem happened was in the late
afternoon when I was sitting next to a bright window. Once the communications
are interrupted, the RCX will not respond again. There should be a way to
handle this type of error and regain the ability to communicate.
Any suggestions?
