GSoC - Implementing one more absolute coordinates device for QEMU – a serial tablet with behaviour like usb-tablet we use to get mouse integration
Main fork with last commits - https://github.com/avg206/fork-qemu/commits/master?author=avg206
I've sniffed protocol between real tablet and drivers in windows 3.11 and windows 98. After it I've created emulator for real device and start testing.
Next chanllenge: driver check if there are real tablet by sending some bytes and wait for encrypted answer.
I've spend a lot of time to understand encryption algorithm, but finally I've done it and tablet start working correct.
Due to this wiki http://linuxwacom.sourceforge.net/wiki/index.php/Serial_Protocol_IV I can say, that it is two almost defferent protocols.
Images and patch to test my work https://www.dropbox.com/sh/6ccp94r2ktk18tg/AACj4qS18XGCSb3SxVlg3uDsa?dl=0 (readme.txt inside)
Work is almost completed, I only need to refactor some parts to meet guide lines.
