I doubt it's possible to redirect conio at all.  One solution, though,
would be to write a wrapper for all your printing which uses conio iff
stdout is a tty (i.e. hasn't been redirected).  The `isatty' function
is good for this -- on startup, check isatty(stdout); if 0, send
output to stdout (== a file) instead of through conio.
