Hi,
FYI.
I just got a brand new Boundless VT520 with that company's "ANSI 2011"
Keyboard, which replaces the old LK41R-AA keyboard.
In trying to get the function keys to work, I had to cobble my own
terminfo.src entry, since the existing vt520 entry doesn't include most of
the function keys. If I blend the entries for "vt420f" and "vt220+keypad"
I seem to get them all.
So I ended up adding the following to my terminfo
vt520ansi|Boundless VT520 ANSI,
use=ansi+rca, use=vt420f, use=vt220+keypad, use=ansi+tabs,
