Anexo:Scan code
Son los códigos que envía el teclado al ordenador para indicar la tecla pulsada o soltada. Su valor no depende de la tecla, sino de su posición, así se consigue que sea independiente del idioma del teclado.
Para el teclado QWERTY americano (104 teclas) con conexión PS/2, los scan codes son:
