What do you need timers for? If you're waiting for data, just use
select(). That even allows you to perform other actions every now and
then.

Linux' serial driver should work interrupt-driven most of the time. Only
in rare cases it'll poll the serial chip, but I think that's not really
your problem.

Please tell us what you *really* need to do. Then, we'd help you.
Sources of your application to comment on weren't wrong, too...
