Linux equivalent of WaitCommEvent

Question

I want to do an evented read on Serial port which will run only when the data is available.

I have tried sigaction but it causes problem when making a highly threaded application, also sleep function seem to work incorrectly according to many forums.

So I am looking for a similar way as in windows WaitCommEvent that is used in MSDN.

Answer 1

The canonical equivalents for linux systems is to use poll() or select() .

Workings are different of course.
