how to enable prink message on EP9307(linux 2.6.8.1)

Hi Guys,

Can some one please show how to enable printk KERNEL_INFO messages to appear on serial terminal. I am trying to change the lcd device driver ep93xxfb.c So i have add some printk messages in the exsisting driver to see the current configuration of the lcd.

The existing ep93xxfb.c has printk command but nothing is displayed on com port.

I just get this on the terminal
