Based on the info from
postings on the iRex forums, I was able to get my iLiad to act as a tablet for my desktop PC. I used the socat tool on the iLiad and stopped the built in X server (otherwise it would sometimes shut down the tablet):
Code:
killall Xfbdev
socat TCP-LISTEN:2998 /dev/ttyS0
On my PC I ran (substitute your IP address):
Code:
sudo socat PTY,link=/dev/wacom,raw,echo=0 TCP:10.0.0.200:2998
I had to update my /etc/X11/xorg.conf with:
Code:
--- /tmp/xorg.conf.orig 2007-10-19 10:31:14.000000000 -0400

The X11 wacom driver would not initialize the tablet correctly and the cursor would always go into the upper left corner , but if I ran wacdump before starting X it would leave things in an ready to go state:
Code:
sudo wacdump -v -f tpc /dev/wacom
With the two-button stylus from my CF-18 Toughbook I'm able to get the multiple buttons and pressure from wacdump and use the extra functions with the gimp.
It seems a good next step would be a helper application for the iLiad that displays a toolbox palette on the far side of the screen and maybe even a small preview of the screen. Sort of like CAD applications that use digitizer tablets, but for graphics.
