    Can we assume from some of your other posts that your OS is Linux (for the purposes of this question).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    I assume you mean lynxOS. It does help to be precise in these things: if you ask your questions with imprecision, you can't expect an accurate answer.

    Generally, with any OS, the expected way you find these things out is to read the documentation. Since there are multiple options to add serial ports to a system (for example, add-on cards) the answer can be hardware/vendor dependent.

    That said, serial drivers usually support both interrupt and polling operation. Applications therefore make the decision to either poll or be interrupt driven, and set things up accordingly for the particular device, rather than checking such things.
    Right 98% of the time, and don't care about the other 3%.
