Usenet is not an instantaneous medium.  Please wait for a response.
FYI, you're not posting to Google Groups, but through it and out
to the Usenet group hierarchy.  I.e., comp.os.msdos.djgpp belongs
to the comp.* Usenet group hierarchy, which is one of nine:

As for your question regarding detecting "Windows NT",
please read the "Notes:" section here and here:

RBIL "INT 21 - DOS 2+ - GET DOS VERSION"
http://www.delorie.com/djgpp/doc/rbinter/id/22/27.html

RBIL "INT 21 - DOS 5+ - GET TRUE VERSION NUMBER"
http://www.delorie.com/djgpp/doc/rbinter/id/41/27.html

RBIL is Ralf Brown's Interrupt List.  It's available in file
form from the original author as well as html via DJGPP and
another website.


Although the original DJGPP contributors should have some deep
insights into your answer of determining NTVDM or Windows DOS
console etc, you're more likely to get a useful response on
comp.os.msdos.programmer or the "DOS Ain't Dead forum":
