Have u referred to the specifications of the same LCD? Because the LCDs which I used -Oriole make - were having 40h as the address of the 2nd line 1st character. For the first line, all the 16 characters were having consecutive addresses. Try making a loop iterating 16 times swarting with the 1st line 1st char address. Just increment the address and change the data.
Also, observe ur code carefully. When u set the DDRAM address to c0h for 9th location, are u changing back the address of the LCD, to write the data? sometimes we forget this.
bye...
