Thanks a lot for your (quick) help. I suspected that, but it was
no so clear and precise :-)

That was more that I was asking for. But it do not seem to work on my
computer. I am using 2.01 under W95. Maybe that's the clue. Should I upgrade to
2.02?

Anyway, I think I'll keep the explicit "setmode(fd, O_BINARY)" call
in my final code so as letting it run and compile under 2.01. I do
not see any major drawback doing so. Are there any?

Thanks a lot for your help.
Best regards,
Philippe
