Question about an item: Rope of Entanglement

[Greenfield]

According to the DMG/SRD, the Rope has an effective range of 20 feet horizontal or 10 feet verttcal, and entangles the target.

So here are my questions:

1) Is there a roll to avoid the Entanglement, such as Reflex? (I know there are rolls for escape, but nothing mentioned to avoid the issue in the first place.)

2) "Entanglement" isn't really a defined condition, other than the spell of the same name. So what does the rope actually do?

It actually is: Entangled

D'oh! Some days I'm dense.

Okay, half the question answered.

If there is no DC or save listed with the item then there is none for it. There is also no attack roll listed.

Given its price, I'd actually kind of hope it's an automatic effect.
