I don't know PUTR, but my experience with DOS
int13 code in RSTSFLX (built with DJGPP) is that it worked fine in a DOS window on Win95.
And that makes sense, because Win95 is basically just a bit of UI veneer over DOS. Win NT
is an entirely different thing, of course, and I would not expect DOS low level I/O to
work in Win NT command windows since those really are not DOS.
Maybe for Win95, but Win98 and later uses its own 32-bit port drivers
(I'm not certain about 95 OSR2).
If running 98 or 95, just do a "shutdown to MS-DOS prompt", rather than
opening a DOS Window and you'll be fine.
