Hi Geert,
The kernel says (ARAnyM, windowed mode):
| Reseting weird mouse packet: 942, 379, 0
| Reseting weird mouse packet: 943, 379, 0
| Reseting weird mouse packet: 945, 378, 0
| Reseting weird mouse packet: 948, 378, 0
| Reseting weird mouse packet: 956, 376, 0
These messages come from ARAnyM.
When running X under ARAnyM (depth 16), some shortcomings show up:
- up and down are interchanged (works fine when rolling the mouse over the
bottom surface of the table --- old arabic map style ;-)
Weird - the inversion of the y direction increment is taken from the old
busmouse driver code where it used to work OK. The point of reference is set to
be at the top of the 'screen' so moving the mouse down ought to generate
positive increments.
ARAnyM's emulation of the IKBD does not support changing the y origin.
- the left and right mouse button are interchanged
The busmouse driver had no annotation as to the semantics of the buttons so O
guessed bit 0 was for the left button. Guessed wrong, it seems.
Note that the mouse button bits are also inverted, ie. 0 means down.
- the middle mouse button is dead
As is expexcted - the original code was for a two-button mouse only. If Petr
knows what the ikbd format for the third button is (on real hardware) it's easy
to add that in.
The IKBD does not support more than two buttons. For a three button
mouse the middle button was apparently wired to the joystick port.
