To my knowledge I believe you can use both commands. The S is for serial. You can make almost any command shorter than it actually is by abbreviating it.

The difference you are seeing reflects different router models used as the basis for the commands.

interface S0/0

This syntax is used on models that have interface slots and each slot can have multiple ports. So, this means slot 0/port 0. You'll see this on 26xx series models. This can also be written out as "serial 0/0".

interface serial 0

This is the syntax for router models with fixed interfaces, like the 25xx series. This notation can also be abbreviated as "s0".

You will also see notation like this:

interface s0/0/0

on modular routers like the 28xx series where a network or interface module can have multiple slots. Here you have module/slot/port. Module 0 is special and indicates a built-in slot.

You need to use the correct syntax for the router model you are using.
