agreed - that interface is all that ncurses provides.

The "mouse pointer" in _xterm_ may be set via an X resource (unless it's
using the cursor-theme stuff).  That's done via XDefineCursor().

       pointerShape (class Cursor)
               Specifies the name of the shape of the pointer.  The default is
               “xterm”.

Technically its color can be set using an escape sequence, but iirc the
required support in the X server has been broken for a long time (due to
some changes for acceleration).

By the way, being a "curses" question, it should have been directed to
bug-ncurses (xorg won't provide any useful insight).
