Parasound zTuner

-- zTuner.lua

-- driver for Parasound Ztuner V1 and V2

-- file version 1.0.0

-- There are many places where we check to see if we are a V1 or V2 tuner

since their protocols

-- are different. The V2 protocol is more straight forward than the V1 as

will be evident in

-- how much extra work is required to setup the outgoing tune commands and

with the extra work

-- required to know what piece of information we are currently expecting

back from the tuner

-- (this is the FREQUENCY_FIRST, LAST, BAND, etc stuff)

-- DigiLinX command handler:

-- function handle_band(command)

-- function handle_clear(command)

-- function handle_key(command)

-- function handle_next(command)

-- function handle_preset(command)

-- function handle_prev(command)

-- function handle_scan(command)

-- function handle_seek(command)

-- function handle_tune(command)

-- Other functions:

-- function CheckPower()

Send command to check power state of tuner

-- function OnAsyncInput(stream, message)
