Preferences have nothing to do with it.  <stdio.h> support is simply
*way* too crude for what you're trying to do.  Remember: this is DOS, not
UNIX you're programming for, i.e. not everything that could usefully be
a file actually is.  COM1: is made available as a file, but it's supported
only on a *very* basic level, by DOS.  You're way beyond the point where
it makes sense to try and rely on DOS to get things done for you.
