Does salt increase heat of vaporization and specific heat capacity??

I'm getting mixed up on what happens when salt is added to water.

There is stronger intermolecular forces in the solution. Melting point depression and boiling point elevation occurs. Does this stronger intermolecular force indicate higher heat of vaporization and fusion? How about specific heat capacity?

Doesn't a higher boiling point = higher heat of vaporization and higher specific heat?

I'm not sure. I'm looking at BR Gen Chem page 89 of a comparison of standard heating curves between pure water and salt solution. The slope during the liquid phase looks steeper (steeper slope is said to indicated less heat capacity).
