UDOO DUAL/QUAD features a built in USB to serial interface which is very useful for various reasons: You can use it to connect UDOO DUAL/QUAD via SSH without a network connection, programming the Sam3x (arduino) and access the debug console for troubleshooting purposes.

Connecting via serial will practically result in a shell console, the same as the one you’ll obtain through SSH connection http://en.wikipedia.org/wiki/Secure_Shell.
