What do you mean by "work"?  Should it produce A-key or M-key in
Emacs?

Sorry for not being clear... I guess this is OT
Best I can see Alt generates nothing
Naturally I would like Alt-x to be emacs' M-x as it does in 
windows and gnu/linux desktops.
In an X env I would have checked with xev.
Here not sure what to check with
No idea what is A-key

By which I mean that there must be some putty setting to make Alt behave like
well like Alt :-).
google was not much helpful

Works for me.  Using putty.exe and emacs in the standard text console
mode and Alt works like Meta by default.  It does this by prefixing
the key with ESC.  That is Alt-x on the putty.exe keyboard produces
"ESC x" sent over the serial data stream.  This can be easily seen by
typing into 'od -tx1 -c' (finish with C-d eof) and looking at the
data.  Command line applications such as bash and emacs interpret "ESC
x" as M-x and behave appropriately.

I looked over my putty.exe configuration dialog screens but didn't see
an explicit option to enable or disable this.  I know I have not done
anything specific in this regard.  It is a feature I use almost every
time I have ever used putty.exe and I have never needed to configure
it explicitly.  It has always worked by default.

Therefore I conclude that it must be something in your environment
that is *preventing* this from working.  I'd say it works for other
people.  You will need to debug your environment and see why it
doesn't work for you.

Looking at things like:
http://blog.sanctum.geek.nz/putty-configuration/

I gather I need to set up a suitable terminfo (on server):

# apt-get install ncurses-term

And then set the $TERM to putty (not the default xterm) on the putty side

[Not on office-machines now so just talk ATM]

Right now tried opening an xterm and typing Alt-x
I get  this (captured with emacs -nw)

            character: ø (displayed as ø) (codepoint 248, #o370, #xf8)

FWIW, my TERM is set to xterm, and it works well.

That's 'x' with the high bit set.  Do you see the same in "emacs -nw -Q"?
What does "C-h l" show after you type Alt-x?

Is this in "emacs -nw -Q"?

Does it help to evaluate this:

  (set-input-meta-mode t)

And what does evaluating (current-input-mode) produce?

Then perhaps it would be wiser to wait until you are on those systems,
and post data from there?

Sorry about that
Its devil vs deep blue sea.

Office: Its a firewalled prison
And I dont understand the environment
And the sysads in charge are not exactly clued in

Home machine(s): I can try things and I am familiar
But its not the relevant system

Anyways Ive learnt some from yours and Bob so far... Will try some more
on Monday

I think this happens automatically with PuTTY.  It does for me.

Are you sure it's not something in your TERM value and the
corresponding terminfo entry on the target machine?  What happens if
you type "ESC x", does Emacs on the remote see "M-x"?  If it does,
audit the PuTTY settings on the PuTTY's "Keyboard" and "Features"
panes (under "Terminal").  Maybe also "Behaviour" under "Window".

alt needs not to be captured by emacs so it can get to putty then have 
putty work.

Cant make out what you are trying to say.
Other way would have made some sense; ie
«alt needs not to be captured by putty so it can get to emacs »

Ok thanks -- will check these (office machine thin clients talking to a VM)
ESC-x works as M-x
