 Interesting!  Most stuff is OK with VT100 instead of VT52.  Is it
 because the VT100 emulation is lacking in its VT52 support, or is it
 because the real VT100 is lacking in its VT52 compatability? 
That was a weird comment.
I'd say no stuff is OK with a VT100 if they expect a VT52. As soon as we 
go outside the plain "output running text", they are different.

That said, a real VT100 can be switched into VT52-emulation, which is 
pretty good, although not exactly identical.

In this case, the poster even was nice enough to tell what the problem 
was. A VT52 will display a block character when you send a DEL to it. A 
VT100 will not, not even in VT52-mode. And I don't think any other 
VT52-emulation I've seen does it either.

In fact, I don't even know if a real VT52 do that. It might be a 
"feature" of some russian VT52-clone for all I know.
I haven't had a working VT52 near me in 15 years now, so I can't check.
