Hello, I'm using Qt for industrial applications, and serial port communications are one of the most important parts of our software.
Qt4 doesn't seem to have an "official" or "supported" library for this, so I resorted to qextserialport (http://code.google.com/p/qextserialport/), which seems to work fairly well so far. However, the project seems stalled (Last commit was in Frebruary 2010) and it starts so show some age: i.e. it fails to compile out of the box on Windows when using a Qt library installed from one of the new QtSDK packages, as qextserialport uses internal Qt4 headers, and the source directory has changed in the QtSDK packages.
I'm also worried about the portability of QtSDK. Will it work on all the platforms Qt4 supports? I'm planning ports of our software for Linux Embedded and WindowsCE, and finding qextserialport doesn't work there would be a huge issue.
In short: are there plans to merge qextserialport into mainstream Qt4, and/or is there any "supported" alternative that will work anywhere Qt4 does?
