NicolasV 0:15536ec3bf58 7 Este programa interfiere de forma loca la operación de un televisor.
NicolasV 0:15536ec3bf58 8 Emite códigos de t.v. con el fin de fastidiar al televidente.

NicolasV 0:15536ec3bf58 10 El control utilizado es de marca Panasonic. Se encontró que los códigos IRDA para
NicolasV 0:15536ec3bf58 11 esta referencia tienen una longitud de 48 bits. Se modificó el programa "Capturas IRDA"
NicolasV 0:15536ec3bf58 12 para ajustarse a esta característica y con base en eso se obtuvieron los códigos.
