Qt and serial port programming

Question

Is there any serial port facilities in Qt ?

If not, which crossplatform (desirable) libraries (for working with serial port and, maybe, with other I/O ports), do you recommend ?

QtSerialPort is included in Qt 5.1 – drzymala May 20 '13 at 17:19 — drzymala, May 20 '13 at 17:19

Take a look at the Project QextSerialPort.

I'm using this at the moment and it works great! Saved me tons of time. – Steve Lazaridis Jun 01 '11 at 14:29

I think the recommended solution is better to be QtSerialPort these days. – László Papp Dec 14 '13 at 15:52

Well, there's always Boost.

In Boost there is a great Async I/O library called ASIO. It can perform operations in all sorts of endpoints, including serial ports.

There is a great example about how to build a minicom-like application using Boost::Asio, that you can use to see if ASIO will attend your needs.

Since boost works on all platforms/compilers under the sun, the cross platform requirement can be checked.

Cheers.

Here is a Qt serial library, works on Win, WinCE, Linux (i386 and ARM), Mac...

Also, it is based on QIODevice for a native feel, with it you can, if you like, direct serial communication onto TCPIP with little no no effort.

It is LGPL also... enjoy.
