The JTAG Widget is completely open. You can execute *any* 
function by sending it parameters and commands. Correct 
execution leads to an "ok" prompt. The software manuals are 
available from:
  http://www.mpeforth.com/jtagwidget.htm

If you are unfamiliar with Forth (the basis of the on-board 
interpreter and compiler), there is also a tutorial on the books 
page for free download.

The PC side of an RDI interface to the JTAG Widget can download
and save (on the Widget) a set of RDI extensions in the same way 
that Flash and CPU drivers can be saved. The RDI extensions can 
use any of the existing Widget functions.

We chose to use the FTDI COMport drivers because they give the 
easiest installation under MacOS and Linux. If you want to use 
another interface style we're happy to work with you on it.
