Why?  IIRC, we decided that a modified X-10 transceiver could be programmed
to act on an escape key.  Press ALL OFF and that's a flag that the next
command is a meta command like a non-default housecode.  I think that was
Dan L's explanation of it, anyway, that with the escape key, you can have a
transceiver respond to all housecodes while you still maintain a default
housecode.  To send a real ALL OFF, you press the key twice within a short
time frame.  At least that's what I hope Jeff was working on or at least a
way for an end user to load a translation table of their own design.

Certainly not a homebrew supertransceiver?  While I understand stock X-10
transceivers are stuck at whatever their housecode wheel is set at, the
Leviton all housecode transceiver will hear and act on any housecode.  Since
I can change the housecode on the UR24A, it *has* to be sending housecode
information.  All I want a transceiver to do is to sense that an escape code
has been hit, override the default housecode and use whatever keys follow an
escape key next as the housecode for any following command.

Buy me six and I will be happy to switch!  I love my UR24s.  They will have
to pry them from my cold, dead hands!  If the IR network and the CPUXA work
together I can make the 8-in-1 all-housecode pretty easily by using IR and
translating all the commands into PLC via the CPUXA.  I'd much prefer to do
it with a Turbo CM15X from Jeff because it's RF and offers the potential for
a security prefix to lock out the neighborhood juvenile delinquents if
needed.

Laugh all you want!  I WILL control ALL 256 House and Unit codes by Remote,
I swear by the name of Al Gore, the Father of the Internet!

They blew it on the ControlLinc - people are used to letter and key
combinations.  There's no need for 16 extra house code keys when you could
press a housecode button first and then just a number key.  Would have saved
a LOT of real estate on a controller that badly needs a size reduction.
