632- adjusting column/row position

i'm using a 632 interfaced to an Atmel micro. my question is this, i'm using the UART to send the lcd data, which works fine. but i want to adjust where certain text shows up, i was trying it like this.
Code:
printf("data");
putchar(17); //tells the lcd to adjust
putchar(0); //column 0
putchar(1); //row 1
printf("more data");
i was thinking this would show up as
Code:
data
more data
on the lcd. it isn't working though, any suggestions?

Hmmm . . . that looks like it should work.

Try:
Code:
printf("data"); 
putchar(17); //tells the lcd to adjust 
putchar(1); //column 1 
putchar(1); //row 1 
printf("more data");
That should do:
Code:
data
 more data
Some libraries go out of their way to have trouble sending a 0, maybe that is what is going on. I would not expect something called "putchar()" to have troubles like that though.

yep that worked. i took it another step and put it in the format
Code:
printf("data");
putchar(17);
putchar(0x00);
putchar(1);
printf("more data");
using the hex value for the column worked, i'm not for sure why though. so now i've got
Code:
data
more data
thanks
