The docstring says

,----
| If called interactively, enable Blink-Cursor mode if ARG is positive, and
| disable it if ARG is zero or negative.  If called from Lisp,
| also enable the mode if ARG is omitted or nil, and toggle it
| if ARG is ‘toggle’; disable the mode otherwise.

To me this suggests that (blink-cursor-mode 0) should disable the
blinking cursor.  Anyway, (blink-cursor-mode -1) makes no difference.
