Using Arduino Displays

Hello Im trying to send a string to arduino from a computer and then from the arduino to the computer
but it keeps sending numbers when I type letters
what code should I use?

what code should I use?

What code were you using?

#include <LiquidCrystal.h>

// Connections:
// rs (LCD pin 4) to Arduino pin 12
// rw (LCD pin 5) to Arduino pin 11
// enable (LCD pin 6) to Arduino pin 10
// LCD pin 15 to Arduino pin 13
// LCD pins d4, d5, d6, d7 to Arduino pins 5, 4, 3, 2
LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);

int backLight = 13; // pin 13 will control the backlight
String g = "";

void setup()
{
Serial.begin(9600);
pinMode(backLight, OUTPUT);
digitalWrite(backLight, HIGH); // turn backlight on. Replace 'HIGH' with 'LOW' to turn it off.
lcd.begin(16,2);
}

void loop()
{
g = Serial.read();
// columns, rows. use 16,2 for a 16x2 LCD, etc.

lcd.setCursor(0,0); // set cursor to column 0, row 0 (the first row)
lcd.print(g);
Serial.print(g); // change this text to whatever you like. keep it clean.

delay(400);

}

Ok, what you see if you open the serial monitor with correct baudrate, can you send anything, do you get it back?
