I have an elevator with three floors, and named them in the Redstone Contacts like so, from bottom to top:

The numbering of Floor Identifier is important to visualize what I'm after here.

I'm running this test code(floors.lua):

e = peripheral.find("digital_adapter")
s = "bottom" --convenience
if e then
    print("Elevator found")
    enum = e.getElevatorFloors(s)
    for l = 1,enum do
        print(l.." : "..e.getElevatorFloorName(s, l))
    end
end

I was expecting e.getElevatorFloorName(s, l) to return the actual names (i.e. Floor Description) but it returns Floor Identifier like so:

>floors
Elevator found
1 : 1
2 : 4
3 : 3

How can I get the Floor Description?
