Adding some code from my program
#define LCD_RX 0x02 // Arduino pin for rx
#define LCD_TX 0x03 // Arduino Pin for tx
#define LCD03_HIDE_CUR 0x04 // Stops the position cursor from appearing on the display
#define LCD03_CLEAR 0x0C // Clears the screen and sets cursor to the home position
#define LCD03_RETURN 0x0D // Carriage Return
#define LCD03_SET_CUR 0x01 // Cursor to a position specified by the next byte, where 1 is the top left and 80/32 is the bottom right
#define LCD03_BACKLIGHT_ON 0x13
.
SoftwareSerial lcd_03 = SoftwareSerial(LCD_RX, LCD_TX); // Sets up serial for LCD03
.
void setup()
{
Serial.begin(14400);

void loop(){
