It sounds as if someone's trying to use TERM=xterm for all three,
which won't work.

Some packagers prefer to number shifted-f1 to shifted-f12 as F10-F22.
Some terminals implement this, some implement F13-F24 (hardcoded).
xterm has a resource-setting to select it -
ctrlFKeys (class CtrlFKeys)
In VT220 keyboard mode (see sunKeyboard resource),
specifies the amount by which to shift F1-F12
given a control modifier (CTRL). This allows you
to generate key symbols for F10-F20 on a Sun/PC
keyboard. The default is ``10'', which means that
CTRL F1 generates the key symbol for F11.
which I added in 2000. The terminfo entries I maintain for ncurses and
xterm reflect the default resource settings. If you want to change the
resource settings, you need a new terminfo entry (suggest doing it with
a script ;-).

by the way, Debian maintains "xterm-debian" - it won't be in ncurses
upstream, nor in xterm upstream.

It sounds as if you want to change xterm's modifyFunctionKeys resource.
