console

I need to disable the serial console or at least move it to a different serial port .
I need to use the first uart.
I have replaced the angstrom distro with Ubuntu and I boot off the sd card as opposed to the MMC.

my distro is
ubuntu-saucy-13.10-armhf-3.8.13-bone30 both on the mmc and the sd card.

can anyone assist me on how to do that

I’ved googled a lot of stuff but none seems to work
