Curses. Elementary problem. Need help.

[Rouben Rostamian]

I need to turn the visible cursor on and off from within an application
program using the curses screen manager.  I do not know how to do this 
and would appreciate any hints and pointers.

Specifics: 
    Machine: DECstation 3100 running ULTRIX
    Program: In  C
    Curses : #include <cursesX.h>
    Display: xterm or vt100 terminal

On one of our System V machines the curses package provides
a command curs_set(int arg) which accepts argument values of 0, 1, 2, to
set different visibility levels of the cursor.  ULTRIX curses does not
seem to have an equivalent command.  Or does it?
