Strictly the way to do this is using freopen() but that isn't fully 
supported by eCos, although it wouldn't be difficult at all - just dropped 
off the end several years ago now!

You could even just do it yourself using fclose() and fdopen() and 
assigning to stdin - there's nothing else required AFAIK.
