None of the X-10 commands apply to the entire X-10 addressing range. The
above commands only apply to the house code that is set on the unit,
unless you have used a single house code for the whole house.

It would be a simple change to the code only if you have the source code.
In addition, the PIC chips used on some of the X-10 modules are custom
chips with no common equivalent available. eg. IR7243.
