A long story with a short response - you are correct for a real DEC VT100.
I have not yet looked at a DEC VT220. On the other hand, my Plessy VT100
terminal works the same as the real DEC VT52.

As for the DEC VT52, with both upper case and lower case, the output
in local mode is ALWAYS "ABC" or "abc" when I type those five characters
in by hand in local mode. I was never able to test in normal mode since
I could not seem to get a cable which worked. I had set up a file with
those five characters which I would have done a "TYPE" in RT-11. Sorry.

Any other sequences?

It took a while, but I finally managed to get into local mode.
But now I think I can't get back into normal mode even though
the switches are in the original position - oh well.

If you attempted to send a reply and the original e-mail
address has been discontinued due a high volume of junk
e-mail, then the semi-permanent e-mail address can be
obtained by replacing the four characters preceding the
'at' with the four digits of the current year.
