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.
