appearance of constant full pressure

Bug Description

With the aiptek hyperpen 6000 (serial) using a ps2 keyboard, the cursor appears to apply full pressure (or a button is depressed). When the pen is so far from the pad that movement detection is intermittent, the pressure appears to be zero (or the button is not depressed). This is tested as corepointer and also just in gimp windowed mode.

I'm not terribly familiar with this device, so if there is any further information I can supply, please ask. I'm also unsure of the trigger condition for drawing in the gimp, so apologies if the above is misleading.

Additional clarification: the full pressure is not dependent upon contact with the pad, but most of the free space above the pad causes this effect.

Xorg configuration:

Section "InputDevice"
        Identifier "Tablet"
        Driver "hyperpen"
        Option "Device" "/dev/ttyS0"
        Option "Mode" "absolute"
        Option "Cursor" "stylus"
        Option "XSize" "600"
        Option "YSize" "450"
        Option "BaudRate" "19200"
        Option "ZThreshold" "100"
        Option "ZMin" "50"
        Option "Pressure" "soft"
EndSection

I wonder, actually, how it is possible for this to work. The device is /dev/ttyS0, yet some of th data comes in through the keyboard - how is this supposed to be configured?

I have an aiptek tablet to and my config looks like this:

    Option "Cursor" "Stylus"

I had the same problem in Debian Lenny - I removed the PMax PMin and Pressure options in my Xorg.conf and it is almost perfect:
Section "InputDevice"
    Identifier "tablet"
    Driver "hyperpen"
    Option "Device" "/dev/ttyS0"
    Option "Mode" "absolute"
    Option "Cursor" "Stylus"
    Option "BaudRate" "19200"
EndSection

Now it senses about 1cm above the pad, but I have to actually touch the pad to make it click. I think that is about right for me, though I might try and play with the PMax and PMin to reduce the hight it senses the pen at

For the question of serial and ps/2, I think the data comes from serial, but it uses the ps2 for extra power - I could be completely wrong though
