Hi Alberto,
Are you the original poster? It sounds like you are, but you have a different Username?
Anyway, yes, I do have an internet connection 24/7, and I understand that it is not easy in some countries to get a good / fast connection at a good price.
However, when I refer to issues I had with mine I didn't use the internet, I did post a question here, but I managed to figure it out on my own, by looking at the datasheet again, which is where I was refering to it taking a bit of patience.
Most compilers come with UART examples, and as long as you have the datasheet and the manuals for that particular compiler / chip it would be fairly straight forward to modify.
The point of forums like these are to help people, by giving tips / pointers in the right direction, not to sell your projects, which is what is happening.
