Pieter,
I'm sorry but I am not able to help you on this one. PCSC is not an area
in which I have tremendous experience.
The following is entirely supposition. It would be interesting to hear
from Someone Who Knows These Things.
My strong suspicion is that PCSC grabs the COM port whenever a smartcard
reader is registered with it since it (presumably) polls all attached
devices to determine if a card has been inserted.
If this is the case then I can't see how PCSC can co-exist with
javax.comm.
I presume that disabling the device from the control panel simply
deregisters it from PCSC which perhaps then ( realizing that it has no
registered devices ) releases the COM port.
Why this would prevent the card reader from interpreting commands sent
to it via the serial port, I do not understand. I can only assume that
the 410P uses some other resources ( otherwise why would it be PnP ).
I suspect that there is in fact a driver for the GCR410P but that it was
installed with the W2K beta and thus not noticed by you.
In summary, I can't help here. It seems as though you are stuck with
using either Windows and PnP with the 410P or java and the 410.
Hopefully I am wrong and someone can correct this perception.
Good luck
Dave Durbin
