So I checked the VT520/VT525 manual and what I found is that neither 
DECID—Identify Device, nor DA1/2/3—Device Attributes requests can be 
used for this purpose, as they both return series of numbers 
(Attributes) delimited by ";", e.g. for VT525 the DA1 Response would be:

CSI ? 65;1;2;7;9;12;18;19;21;22;23;24;42;44;45;46 c

That doesn't suit our need to transfer a string.

That means we probably need to incorporate a new Escape Sequence for 
this (only if other terminal vendors didn't provide some suitable one).
