At Jean-Luc's request, here is the support response I received regarding
the GPR400 and Cyberflex Access cards. The same information can be
found on the Gemplus developer website - I've seen it there.

I removed the Windows Help file attachment. If anyone needs it, let me
know. I'll then put it up on my website.

I read it as, I need to patch the GPR400 driver to work with the
Cyberflex Access cards. Specifically, the GPR400 needs to be forced to
communicate at a certain data rate. The sample code given seems
specific to the Gemplus Windows API (or at least a higher-level API than
I have access to.)
