Strange, I thought stack trace back was a standard feature of symbolic
debuggers.  Is there something about AVRs that makes this difficult?

That was my thought but, since I'm new to AVR I thought I'd ask.

Thanks for that ...

BTW: I checked out your web site.  Can you briefly describe the "RTD Serial
Protocol Analyser" and "RTD SIP Simulator/Analyser" programs you have on your
download page?  RTD => as in Temperature Sensor?

I've been to Australia twice - great place you have there ...
