I bought a second Uno board, first being Duemilanove. I struggled quite some time till both boards started working.This piece of information is for those who are like me still struggling to get acquainted with these toys.I was getting one working while other couldn’t. These two have serial ports Com1 and Com3.The ports were being identified correctly; however small tick before Com1 or Com3 was solved the problem. If the board has correct port with a tick then only the program works!
