I think you're doing it the right way, just keep in mind that DJGPP
programs have to move all that data back and forth between DOS memory
and DPMI memory.

You might want to use open/read/write/close instead of
fopen/fread/fwrite/fclose though.

Or, even faster, _read and _write, although then you have to deal with
all the odd DOS border cases.  That does bypass the CRLF code, even
though you've disabled it there's still a check to see if it's enabled
for each read/write.
