Watchdog in Arduino Library - or at least support by bootloader

thank you west fw.

seems from what I read that it could be construed that arduino is not one product.

to answer an earlier comment, I like the mega, and I have the official IDE that comes from the arduino web site,
as in here

would be nice if there was an example I could use, same as we have examples for things like lcd's in the ide.

how about an example,

suggestions.
print out to rs232 message.
flashes the led, using say delay
that needs say a key to be pressed on the terminal within say 10 seconds,
if you press a key, led stays on for a second,
if you don't press a key in time, program resets

just an idea,
thanks
