Or you can mark "Disp CV and Disp EP" in the components Display tab of the Attribute Editor or chose Display > NURBS Components > CVs. Another option is set them in the Preferences window. It won't show CV numbers, but at least you can tell which direction your curve is pointing.
If you wanna know the CV numbers, see the Components tab of the Attribute Editor or you can clik "CVs" in the Channel Box.
In Softimage 3D, I can see the starting part of the curves as red.
Does anyone know if Maya can do this?
