Very odd. I had a similar problem trying to use the IDE Serial Monitor at 115k baud which worked ok at lower baud rates, sorry to hear that didn't fix it for you.Other things to try:Try the example ASCII sketch (your sketch sends a cr as the first character and perhaps the IDE is doing something odd) [size=12]Tried ASCII Table at 9600. Same result calling terminal displays data, IDE will not. [/size]Try the dimmer example sketch to see if you can send data to the board.Try setting the IDE serial port to know good serial device and see if you can see that data.[size=12]I am not sure what you mean by last two suggestions. I use the USB port (/dev/ttyUSB0) to upload the program, and I can see the return in the terminal I use to call the Anduino IDE, so I know the port works bidirectionally.[/size]Good luck
Strange. When you upload a sketch, for example, do you see text in the black area at the bottom of the IDE?
So you never see any text in the black area at the bottom of the IDE? Whether you run from the terminal or not?
