Random questions.

1. Is there an easy way to identify from BASIC, a computer which is
connected to a DVI.
2. Is there a range of memory that I can access from BASIC that mirrors the
DVI screen contents?

Basically, I've updated Text Sweeper to properly ID the model 200 and check
the right LCD memory locations, but now I am facing a similar issue with
the DVI system.
