The new 2.1.3 Version of pbForth has only minor fixes thanks
to the investigative efforts of David Rojas and Rob Harvey. They
were able to provide detailed, reproducible bug reports, which
makes fixing bugs so much easier. Thanks guys!
Here's what has changed...
1. Fixed stack error in SOUND_TONE. It used to leave an extra
parameter lying around on the stack with predictable results if
you use this word in a loop.
2. Fixed a nasty communications bug which made the RCX hang under
certain conditions - like shining a bright light at the RCX. The
serial interface on the micro does not set RDRF if the character
has an error.
Here's where to get the new files:

Remember to send me an email if you are using pbForth in schools or
if you have a website with some interesting bots programmed with
pbForth!
Please give it a try and note any installation problems.
Report any problems to the robotics.rcx.pbforth group
at <http://www.lugnet.com> or send me an email.
And be prepared for a nice surprise in a few weeks. A well-known
pbForth user is just about ready to release some VERY interesting
software....
Cheers,
