Re: LYNX-DEV Lynx for a blind user

[Michael Sokolov]

David, you are misunderstanding how a DOS extender works. DOS extenders don't
_decide_ how to do something like screen output, they merely do what the app
itself asks them to do. If the app writes directly to the video buffer, it
would do so regardless of whether it runs under a DOS extender or not. If it
issues DOS or BIOS calls, the DOS extender would have to translate them into
real (or V86) mode, since it doesn't know how to handle them itself (that's why
it's called a DOS extender and not a DOS replacer).
As far as Lynx is concerned, you need to look at how the PDcurses library
writes to the screen (directly or through BIOS), rather than worry about
DGJPP's DOS extender.

Sincerely,
Michael Sokolov
