I'm sure this code really clever...however hard to figure out exactly what it does as the sub uses some globals as well as parameters passed to it, and also invokes some (undocumented) look_down and as_text subs attached to hash structures.
from a modular code design and maintainability perspective not great code to work with.
i suggest you contact the author of the code, rather than putting the named author's code up for review/explanation in this separate post.
the hardest line to type correctly is: stty erase ^H
