AVR-Chat

I found part of it.  One spot in the AVR plugin was set to Mega16 
instead of 90S2313.  Once that was changed then it compiled, downloaded 
and ran properly.  But NOW it refuses to program again, even with a -F 
(force) in avrdude.  Avrdude defaults (and I don't change this) to 
"safe" mode and won't let you change the fuses unless you explicitly say 
to, so the fuses have not been changed, but I still can't get it to take 
a program now.  Some days are like this...

thanks all,
DLC
