Qt and serial port programming

Question

Hi, folks !

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 ?

Answer 1

Take a look at the Project QextSerialPort.

Answer 2

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.

Answer 3

Use QSerialDevice

Answer 4

Thank you kuzulis! QSerialDevice works fine! If there is a chance to do the task in Qt, I would never select boost as alternative.

Answer 5

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

http://gitorious.org/inbiza-labs/qserialport

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.
