Hi folks, I have a G4 Mac Mini and an Alps Glidepoint touchpad which has a serial interface. I also got an Aten RS232-USB adapter. The adapter has drivers for OS X, WinXP and installs fine. On WinXP, the touchpad shows up as a serial mouse, which is fine by me. You only get the basic functionality - move mouse pointer, tap-to-click, double-tap to double-click. So no special stuff like scroll zones, right-click zones, all that. However, whilst the Aten adapter is detected fine on OS X, it does not auto-detect the touchpad. The adapter comes up as /dev/tty.usbserial0. If I open the file manually, and try to read it, I can see characters being generated when I try to use the touchpad. Also the LED on the adapter blinks (otherwise it's completely off, meaning that the OS doesn't open the file automatically). So how can I make the OS use the tty as a pointing device? Is there such a thing as xorg.conf for the UI? If it's not possible with Aqua, could it be possible with X11? (Although I have not been able to find Apple X11's "xorg.conf"-like file.) Any suggestions much appreciated.
