Hi CLUEbies,

Thanks Michael for your response.

The synaptics driver doesn't do DeviceOn/DeviceOff but it does use a shared
memory area which could be used by the calibration program to communicate
with the driver, and the driver of course will communicate with the hardware.
In this way the driver would not need to be unloaded/disabled using DeviceOff -
the calibration program would just talk to the hardware through the driver.

Thanks for the idea!

Also does anyone on the list have the O'Reilly X Window programming reference
book "Volume 9: X Window Programming Extensions" (Adrian Nye, 1996)?  We kind
of need to buy it or borrow it but it seems to be out of print and unavailable
through the usual channels.  If so could you please contact me off-list?

Thanks,
Jim
