Windows programming in Qt (serial communication)

[bnilsson]

Hello!

I want to write a Qt application that will use serial communication on WinXP hardware.
Qt is cross-platform while serial communication programming is not.
I have VERY little knowledge about Windows programming in general, while I have made som working stuff for Mac and WinXP using Qt, where you never see the platform specific calls.

I have written a serial "driver" a long time ago using another cross-platform framework, but it does of course not compile in Qt, but I have the basic functionality. I was using Codewarrior and CPLAT, which are both more or less dead nowadays. Qt seems to be a worthy successor, I like it very much.

Now, how do I write a Windows-specific class inside a Qt project?
What headers should I include to have access to HANDLE and DCB structures, hComPort, etc? What Windows libraries do I need?

Any help is appreciated.
