Not sure what you mean. My code calls different built in functions from
windows. (Like Ipconfig, ping etc.)
The only thing I do is call them from python, make sure that the format is
right and write it to a file. (called temp.txt)
Once temp.txt is complete it goes through a script which makes the text
'cross platform' so it shows 'nice' on forums.
I'll make a little attempt to this. Not sure how it will go.

Yes the scan() functions are external to the GUI. I simply made the code
first and the GUI later.

I'll take your word for that. ;)
