I'm running Linaro Ubuntu 12.04, I have graphical desktop up and running, and I can run the Arduino IDE there. I can write sketches and they get uploaded correctly and they run the blink test, no problem. The IDE says it is using /dev/ttymxc3. How can I read data from Linux that I print out from my sketches? I'm attempting to use Serial.println(), should the text show up on the IDE console? Where does it go and how to I read it? The Serial.available() method appears to succeed (the only way I can tell is by blinking an error if it would fail).
