Dear all,
I'm not an expert of smart card readers nor of APDU commands but I'm
developing software that uses a mix of PKCS#11 modules since some time.
I gave a look to proto-t1.c but for sure you cannot guess the real
meaning of the error without sufficient background.
Using a new smart card reader, I'm experiencing some slowdown in
communication with the smart cards and I see this error in the logs:
proto-t1.c:479:t1_transceive() CT sent S-block with wtx=1
As the operations are completed anyway, so I guess this is rather a sort
of warning, but what does it mean (in human terms)?
Is there some issue in the communication and the driver must cope with
it by resending data (hence the slight slowdown)?
I'm currently forced to use old versions of the software involved (see
later), so the second question is: should I care about the error? What
could the consequenses be?
DETAILS:
system: Red Hat ES 5.4
SW versions: ccid 1.3.10, pcsc-lite-1.5.3
+ [opensc-0.11.8.tar.gz] + [pkcs11-helper-1.07.tar.bz2] + proprietary
PKCS#11 module libbit4ipki.so for InCard smart cards (version not available)
