USBIODS MAC OS X 10.0 Driver
Version 1.0 Beta

Here's the completed framework.  
It lacks an installer, so you will have to manually install it. 


gnutar xvfz MacOSXRev1.tgz

to produce:

MacOSXRev1/
MacOSXRev1/DelcomUSB	<- source for test and framework
MacOSXRev1/DelcomUSB.dst <- root

To install, you can:

cd MacOSXRev1/DelcomUSB.dst
sudo ditto . /

(This copies the framework to /Library/Frameworks/DelcomUSB.framework, 
and the test tools to /usr/local/bin/)

The test tools are:

dc_reflect: reflect pin0 inputs on pin1 outputs
dc_raw: similar to your DOS tool, where you enter the commands yourself
dc_runninglights: back and forth.
