ok background I have my own 'duino clone all seems to work fine loaded blink sketch LED blinks so far so good
the sketch starts by setting the LED on for 1 second in setup() then sends SOS in morse code ok it's silly but that isn't the question
when I hit the reset button (which hold RESET signal low) I get a couple of flashes on the LED, then 1 second on, then morse code sequence starts
is this expected behaviour?
(well I didn't expect it!)
