color=#0000ff size=2>BTW, I know that the DEC PostScript/SNMP printers of my
generation, that is, until early 2000, did implement this feature. Don't
know if customers used it. But that is not the point.</FONT></SPAN></DIV>

color=#0000ff size=2>Believe it or not, the equivalent of ConsoleDisable for
desktop monitors is among the most-requested features from large businesses
these days. They call it ConsoleLock, but it's the same thing: don't let
the user futz with the buttons. Yes, it does require that one re-enable
the console for a service call, but apparently it also makes service
calls less frequent. Go figure. </FONT></SPAN></DIV>

is a useful and desirable feature, and I think we should carry it forward in
future standards. </FONT></SPAN></DIV>

<DIV><SPAN class=130062118-20042007><FONT face=Arial color=#0000ff size=4>Well,
hypothetical capability today in Printer MIB... The

encountered</FONT></SPAN></DIV>
<DIV><SPAN class=130062118-20042007><FONT face=Arial color=#0000ff size=4>a

<DIV><SPAN class=130062118-20042007><FONT face=Arial color=#0000ff size=4>Now,
remote reset of the printer actually does make sense (via a

color=#0000ff size=2>I was not proposing any analogous property at all, but an
empty class with only the method to change the state. What I intend
is having a class to represent the function of the property we don't like.
And the class has a RequestStateChange() method to effect the function.
And the enabled-disabled state of the class shows up in the existing
EnabledState property. </FONT></SPAN></DIV>

color=#0000ff size=2>This is the *last* thing I would do to the new model, after
adding all the other stuff as read-only as we agreed. Or rather, the first
thing of the new writable model, the pipe cleaner for putting write functions on
various properties. </FONT></SPAN></DIV>

color=#0000ff size=2>We have the capability (pardon the expression) today, at
least in the model if not in many implementations, to disable console
input. If we can model the capability in another way that does not
expose a dangerous writable property, that seems like a good thing.

<P><FONT face=Arial size=2>Console. Not ConsoleLights or
ConsoleDisplayBuffer, but a class with no properties other than state so that it
can be enabled and disabled. In the voting spreadsheet from eons ago, we
all voted prtGeneralConsoleDisable as priority A. And there is a comment
on it that says, "must be implemented as CIM state accessible by
RequestStateChange() method." Who would have guessed that we had such
foresight way back then. </FONT></P>
<P><FONT face=Arial size=2>Proposal: When we get to it, we can use this as a
pipe cleaner for CIM modeling of this writable property. I think it
results in an otherwise empty class derived directly from
EnabledLogicalElement. No new properties, just the state properties and
RequestStateChange() method inherited from the parent. </FONT></P>
