special-protocols: Device Select
--------------------------------

The 7541, 7560, Outlaw, and Replay remotes all have an EEPROM 
position for an extra device.  The 15-2116 and URC8910 remotes
seem to have EEPROM positions for 7 extra devices.

Unlike the 7'th device of a URC6800 or 5'th device of a millenium 
4, there is no built-in code that can be put in a macro to make the 
remote think you pressed the missing device keys (of the remotes
listed above).

This special protocol lets you define a Key Move that will do
device selection of any device index on any model remote.  This is
intended primarily for the cases (described above) in which the
remote has EEPROM space reserved for extra device(s) but does not
have a built in button code for selecting those device(s).

Install the protocol and device upgrades. Create a key move for
which the hex code is the device number. Be sure to hit the "radio
button" in IR that specifies hex cmd, not EFC.

Devices are numbered from 0. For example in the 7541 the devices 
are:

Sat = 0
TV = 1
VCR = 2
AUX = 3
extra device = 4
