Hello,

I apologize if my English is not so good.
I use QT4 to develop applications for Windows and Linux, in both desktop and embedded environments.

I need use a lot of serial connections (often I have 4-5 serial devices connected) so I'm looking for a *reliable* and complete serial library. I don't understand why QT4 doesn't support serial communication natively, I think they are used a lot in embedded applications.

Anyway, I'm playing with the Qextserial but it seems to me a bit buggy and it has many limitations.

Please, may you suggest me a complete serial library that:

* works under Windows and Linux,
* uses signals to tell when data is ready to be read (with buffer thresholds)
* has a working lineread() method
* enumerates available ports under both Windows and Linux

I'm asking too much? What do you embedded programmers use?

Thanks
