I tried using the screenInfo everytime the x,y position is scaled and
returned, but that does not seem to help. I do not know how to support
screen resolition changes. If anybody has an idea, let me know.
The driver is basically a slightly massaged dmc driver, there is probably
still some stuff to clean. Here it is as a shell archive (don't know it
the maillist rejects attachments...)

I have my driver for the serial MagicTouch touchscreen working. There is
just one thing that I am not sure of: if the resolution is changed
dynamically (by some program running fullscreen for example), the scaling
is off. How do I find if the resolution has changed ? Right now, I check
the screen size when the device inits, and store that away. Should I
instead use the actual screen size everytime through screenInfo ? Is that
safe ? Also, how can I twiddle the DTR, RTS lines, I do not find some
abstraction for that...
Maybe xf86SetSerialModemState() will let you twiddle the DTR, RTS lines.
I haven't looked at that stuff in a while. Perhaps someone else can give
you some answers to your other questions.
then, how do I submit the driver ? send it to this list ?
You can either send it here, or submit it at bugs.xfree86.org.
