Reporting some bugs

Post by JamesZ »

Hello,

I have write a driver in C language to command the screen, and I remark some bugs which I want to share with you.
I met some problem with commands like:
- Get Background Drawing Colour, which didn`t return the correct message.
- Manual update which has a wrong second parameter in the GTT protocol reference, (version 1.0), which is initally 89, but it is 91.
- Get String Extents, which has a wrong second parameter, initially it is 252 22, but it is 254 42 in reality.
And I had tried to set and get the control character mode but both didn`t work!
And finally, I have noticed that the Clear All Bargraphs command didint clear the drawing bargraphs, but just the values.
Have you ever see this kind of issues?

And I want to know if someone succeded to implement special characters in the font generator ( for example "
