Text uLCD-144

Hi, i’m having a problem with my LCD. I can send commands, I know this because I can send it a command to give Version-Device Info Request.

The code is:

void setup()
{
Serial.begin(9600);
delay(1000);

Serial.write(0x55);
while(!Serial.available());
Serial.print(Serial.read(), HEX);

Serial.write(0x56);
while(!Serial.available());
Serial.print(Serial.read(), HEX);

}

void loop()
{

}

But now I want to write text, here’s the library of commands http://tronixstuff.files.wordpress.com/2011/02/goldelox-sgc-commands-sis-rev3.pdf.

Any help would be greatly appreciated.
