asterisk users - Mar 2011 - console.conf.sample in 1.8.3

In console.conf.sample it says run the command "console list
available"
CLI command.

It does not seem to be present:
 console list available
No such command 'console list available'

These are the only console commands I see:

                console answer Answer an incoming console call
            console autoanswer Sets/displays autoanswer
                  console dial Dial an extension on the console
                console hangup Hangup a call on the console
             console send text Send text to the remote device
console {mute|unmute} [toggle] Disable/Enable mic input

Is chan_console just a super set of chan_alsa?

In 1.4 Console/Dsp was ALSA, is Console/DSP now chan_console?
In 1.8 what do I use for ALSA?

Thanks,

Jerry
