I'm looking for something which will allow me to make sense of the
various codes returned by VTnnn (nnn>=100) terminals when they are hit
with a 'what are you' sequence.  E.g. ESC[?1;<n>c seems to indicate a
VT100, where <n> is between 0 and 7 and (I hypothesize) somehow
indicates the presence of optional features.  An emulator we've got
which claims to look like a VT320 says ESC[?63;1;2;4;8;9;15c; another
which claims to look like a VT200 says ESC[?62;1;2;6;8;9c.  Again, I
hypothesize that the first number indicates type, and the trailing list
indicates features.  Specific things I'm looking for are:

1) How much of the string do I need to look at to determine the basic
terminal model, and what value(s) correspond to what model.  (This
would be enough info for my basic needs.)

2) (Less important) Does the rest of the list indeed indicate
subfeatures, and if so, which values indicate what features?  Do these
values have the same, or similar, meanings across models?

Does anyone have this information in a form that could be emailed to
me?  Or, is there some official 'summary' DEC document that I could
order from DEC UK as an interested individual who doesn't have a
customer account?  (I don't REALLY want a complete set of DEC
VT-terminal manuals.)  For my purposes, info up to VT220 would be
sufficient, as we don't have many higher numbers lying around.  Out of
general curiosity, though, info on higher models would also be
interesting if you've got it.
