It's written in Qt (Qt3, however) and should compile for both windows and linux. I used some compiler directives to detect the platform and use the appropriate pieces of code. Look for the files called serialio.cpp and serialio.h in the "loader" folder. It's a class with functions to send and recieve data via the serial port. You should be able to use it as a starting point.

I have to warn you though that I have yet to figure out why it doesn't work on Windows XP. As far as I can tell, my code is correct. When I compile it, I don't get any errors. Interestingly the same binary will run correctly on Windows 2000 and WINE, but it will freeze on Windows XP.

For one thing I am using Qt 4, which seems to be quite different for Qt 3 form everything I have read. I still have to figure out how to pull the data form the sliders so I can send it in a struct over the serial port. As you can see I am new to this stuff so I am going to try Visual C++ and .NET 2(hopefully they will make life easier) but thanks anyway.

You can use VC++, but I use C#. You need to look at the System.IO.Ports namespace on MSDN. You are going to want to use the SerialPort class. A couple of examples (in C#) can be found here.

As for the UI, the windows System.Windows.Forms library is very easy to work with and has lots of controls. You can use the Trackbar control (which is the slider) to get input values and then send them to the RC with the serial port.

First I would like to say thanks to everyone that helped. I just downloaded C# and it seems quite promising for me (a beginner). I am currently playing with it and we will see how far I can before I have questions again.
