Yeap I tried that one but it just blow me up. I run DJGPP on WinDOSBox.
I don't know what happened but fprintf,  putc etc.. just won't work.

Is there a problem with this simple (overdefining) lines?

FILE *_outfile  =  fopen("test.zzz", "wb");
fprintf( _outfile, "%1c",  (char)10&0xFF);

Do you have hardcoding technique to stripe the 13 in front of  control key
