Yes I did. The low-level docs I have on the GPR400 don't say anything
about special commands. They *do* indicate that the reader does some
interpretation of the ATR and auto-configures itself to T=1 if
necessary.
I found a post in the dev forum that indicated that the GPR400 may not
have any way to forcefully set the communication speed.
The docs don't seem to say either way.
This lack of clarity in the docs is what led me to contact Gemplus to
begin with. I was hoping they would give me a GPR400 specific command
that I would know works.
I suppose I'll just try sending 0x23 0x01 0x00 0x3E 0x01 TA1 to the
reader and see if it works.
