Clamped cubic spline

I am making a shape by getting Mathematica to draw a smooth curve 
through a set of points.  I want to set the slope of the curve at the 
endpoints. The slope at the endpoints will either be vertical or 
horizontal.  I understand that a clamped cubic spline should be able to 
do this.  The SplineFit package doesn't have clamped cubic splines.  
There is an old MathSource package which I couldn't get to work.

Any help would be appreciated.
