marlonfulla 2:ff11ef31aee5 2 Este programa realiza el envio de ntransacciones, cada una conteniendo una cantidad de bytes igual a ncaracteres, donde cada
marlonfulla 2:ff11ef31aee5 3 uno de ellos corresponde a un caracter que por defecto es la letra A. Entre transacciones existe una pausa de tiempo igual a delay para
marlonfulla 2:ff11ef31aee5 4 estudiar el proceso de liberación del buffer de recepción.
