I forgot something in that last piece about the partial code list
for VT52 and VT100...

The keypad is also different from one to the other.
PF 1-4 is <SS3>P,Q,R, or S for VT100, <ESC>P, Q, R, or S for VT52
Keypad is as follows:

Numeric:               0 1 2 3 4 5 6 7 8 9 - , . Enter
Application base char: p q r s t u v w x y m l n M

VT52 adds <ESC>? before the base char for application mode
VT100 adds <SS3> before the base char for application mode

VT52 cursor keys are <ESC>A, B, C, and D (up, down, right,  left)
VT100 cursor keys are <CSI>A, B, C, and D for normal mode,
                      <SS3>A, B, C, and D for application mode

<SS3> is an 8 bit DEC ASCII code, $8F, which may be represented with <ESC>O
<CSI> is an 8 bit DEC code, $9B, which may be represented with <ESC>[
<ESC> is ASCII code $1B

Have fun...
