And so on. I tried resetting the board, but I got the same. Then I tried re-uploading, but I got an 'error compiling'... I closed the IDE, and re-opened it, now I was able to reupload your code, but still the same characters... Has it something to do with the fact I try it with the serial monitor?
EDIT: when I tried to open up a serial example and upload that sketch to verify my serial works, it also had to reopen the IDE and then it worked fine...
