OK, thanks.

Unfortunatly:

- dvi2tty

doesn't handle words splitted by tex formatter,
i.e. soft or syllable hyphens are still visible as

Char: - (45, #o55, #x2d)

long lines stay splitted.

Also backaddresses underline isn't removed.

- catdvi

fails with: bytesex.c:59: u_readbigendiannumber: Assertion `count <= 4' 
failed.

- crudetype

seems difficult to install, longs for `Tangle'


As a solution at least for tex-documents build with
Dinbrief wasn't far away, I proceeded so far.
