But no serial support
Authored by: thinkyhead on Mar 16, '04 08:05:43PM

Alas, there is no support for old serial Wacom tablets hidden in the Ink stuff. So it's back to the drawing board for me! Maybe you'd like to assist my courageous effort to bring serial tablets to life under Mac OS X?

I've written a REALbasic application that talks to my old Wacom ArtZ-II tablet through the serial port (a Keyspan adapter) under Mac OS X. It interprets UD-II and WACOM-IV protocols and allows me to draw and erase in a small drawing area in the application. I wrote this program to prototype the code to interpret these protocols with the intention of eventually making a driver for these old tablets. Unfortunately I'm not experienced enough with Cocoa to go much further. Howver, I've developed three possible approaches:

1. Write an IOKit driver that communicates with the Wacom serial tablet and then exposes it to the system as if it was a USB tablet. Pros: In theory this would allow the tablet to work with the Wacom USB driver control panel, meaning I wouldn't have to write my own. Cons: IOKit is tricky to write for; Pseudo-USB devices may not be possible; Wacom's driver and control panel may not like such an arrangement.

2. Write an IOKit driver for a serial device - the tablet - and implement everything, including a custom control panel. Pros: Total control over the implementation. Cons: Much more work; requires IOKit knowledge.

3. Write an application that receives the tablet stream from the serial port, parses the stream, and passes tablet events to the Window Manager. Pros: Ink and other tablet APIs in Mac OS X might already have hooks for parsing UD-II and WACOM-IV protocols; Applications are much easier to write and debug than drivers; More stable product. Cons: It may not be possible for an application to send tablet events to the Window Manager in this manner.

I like the third approach best, for obvious reasons. Any help with this project would be much appreciated. I'll be releasing my REALbasic Wacom serial probe publicly very soon to try to garner more interest.

Yeah, I have one of those guys too. I also bought one of those KB Gear Pablo tablets because it was USB and mentioned Mac support (although that is only OS 9).

Well, I broke down and went ahead and bought a new Wacom tablet at Macworld Expo.

TabletMagic posted

I've posted my tablet software here:

I broke down and decided to make my own driver in C++. TabletMagic is the result. Full source code is included.
