I believe some hooks to the IOKit will be required to communicate with the (POSIX) serial port, meaning it would likely have to be implemented in the limited subset of C++ required for IOKit drivers.įrom my investigations I've determined that the most promising course for making serial and ADB UD tablets work on Mac OS X is to make the Wacom tablet appear to the OS as if it was a newer USB Wacom tablet, and then the Wacom drivers would happily do the high-level interpretation. If you would like a copy of this application and believe that you can write an HID driver I would be most interested in assisting you. It even lets you draw lines in a little graphics control. I have fully implemented the Wacom UD protocol in a REALbasic application that reads a serial Wacom tablet, dynamically displays the state in a window, and allows you to send commands to the tablet to change its mapping, etc. You're in luck, strobe! The Wacom protocols are documented in the Developer section of Wacom's web site.
