Strange, it seems to be working here...

If you like you can send me the list file, so that I can compare
instruction for instruction what happened.

Hello
I was on holidays,
Thank you very much for your help.
I discovered that the code works.

There were optimizations at the project options, it was set for speed, once i removed the optimizations the code start working.

Hello,

I forgot to add something.
The uprintf function wont work when it is on its own (in uprintf.c file) I had to move the function inside the code (where i have the specific function to write the characters to port o to buffer) and then is when it works.
If the uprintf is on its own is when it doesnt allocate the va_list.

Thanks
