The data has a form and protocol determined by agreement between the parties at each end. For instance, it could be pure ASCII text, such as might be sent to a Model 33 TTY or a glass teletype. On the other hand, it might be wrapped in a protcol containing a header followed by a message followed by a checksum or CRC. Special codes might be used to indicate the beginning and end of these sections. It depends on how serious error-free transmission and reception is. The output from a temperature-measuring device is probably relatively simple. Just get the manual for the device and read it. Sellers of these things don't require you to guess and iterate to find an answer.

The best way to find that out is to read the actual source of the projects. They are both written in pure python, so it shouldn't be too difficult.

Is using C# a possiblity for this project? Serial port access in C# is really simple.

With the right library, it's easy in any language:

 C# Syntax (Toggle Plain Text) 
SerialPort port = new SerialPort("COM1", 9600);
port.Open();
port.Write("Hello World");
port.Close();
SerialPort port = new SerialPort("COM1", 9600);
port.Open();
port.Write("Hello World");
port.Close();

 Python Syntax (Toggle Plain Text) 
port = Serial(0, 9600)
port.write("Hello World")
port.close()
port = Serial(0, 9600)
port.write("Hello World")
port.close()

I know almost nothing about MS products. If I'm going to use one, I need a GUI builder; so far I've been using wxPython. I found MS Visual C# via searching, which appears to be free. Do I need the .NET portion? Is .NET free? Does Visual C# have any advantages over Visual C++?

If you want to use .NET, I wouldn't bother with C++ .NET - it's very different to normal C++, and would be just like learning a new language. And it's more convoluted than C#.

Visual C# Express is free (http://msdn.microsoft.com/vstudio/express/), and you get a decent GUI designer. Of course, if you already use wxWidgets, you might find something like C++ or even Python easier with the right libraries.

Ooble pretty much covered it. VC# 2005 Express is free. It has a great GUI designer. I've seen you posting Java around the forums, and C# is pretty similar to Java.

The only requirement is going to be that the machine you are running this on will need the .NET framework installed. Since you mentioned that it's going to be Windows XP, odds are it's already installed, but if not it's free anyways. I wouldn't say that it's any more restricting than having to have the JRE installed.
