no lo creo que haya movido algo.. pero por las dudas. aqui esta el ex_tones
y luego te pongo el driver tones.c.. bueno yo creo que hay algo de malo aqui en el driver .. ya que cuando compilo..se va al ventana del driver tones.c y me remarca creo que el problema.. la primera C que la pongo en negrita de la tabla del driver.. mas abjo esta todo completo tal cual lo copie de verdadero archivo para pegarlo aqui.
