That's because for the LCD, the \r and \n are just ASCII chars 13 and 10,
and translate into what the datasheets lists in the character map. You have
to write a function that parses such a string and translates the \r and \n
into a control command to the LCD to move the current pointer to the desired
postition.

Hi.

I have question on UART and LCD control.
I have somehow implemented UART function and it seems to works.
But there is a problem. odd character is printed other than I have
expected.
I tried to print "\r\nStart of  Root\r\n\r\nEnd of Root\r\n"
But the following is printed
--
&#4294967295;&#4294967295;


Start of Root
}&#4294967295;&#4294967295;


End of Root

I have no idea why this happens.

Another question is on LCD control.
I am using samsung 2410 which have LCD controller. Please explain me
some concept on controlling LCD with built-in LCD controller. 
I have examined the part of datasheet, but concept is not easy to
build.
Please answer.

Thanks.
