Unless the new remote is a Pronto-based remote
using the same hex notation, you are SOL unless
you find a utility in a location such as the JP1
forum on Yahoo where John Fine and those wonderful
folks support other remotes.
You are correct - but I'm finding that more and more vendors are accepting the Pronto HEX codes (Universal Remote does (sorta) - and now all the Control4 stuff standardizes on it).
