What devices are you needing the discrete codes for? Some devices do not have discrete on-off codes, they use a toggle (TOADS).
In the files area of this website there is a Pronto section and it has most of the discrete infared hex codes known and also directions on how to use them. Check it out and see if the device you has is listed. Also ask the question on the regular Pronto forum as the discretes should be the same and somebody may have them for you.
