Another possible solution is to use Brian Ingerson's Inline.pm and code
the reads &c. with C's lower level IO. I think a C getc() would do
it....
But be warned that, while it's actually quite friendly, a raw beginner
might have some trouble with the Inline stuff, especially if they don't
know C. I'd say look, maybe try, and decide based on your own
confidence.
Good luck.
