Dear OpenSC developers, it seems to me that there are some myths in the OpenSC community about the send/receive limitations of cards and readers.
In OpenSC there are two places where limitations on send/receive sizes could be imposed. These are based on capabilities of cards and readers. Maybe there are cards with limitations, but at least ACOS5 and STARCOS shouldn't have. The ACOS5 manual states that it supports PUT DATA with Lc=255 (Section 5.28) and in the driver Le=256 is used several times. The STARCOS 1.2 manual (published in 1996) doesn't state anything on send/receive limitations. Other candidates are westcos, which isn't a PKI card anyway and entersafe with manual available only under NDA. Complete list of effected cards looks like this: acos5, akis, atrust-acos, entersafe, gpk, miocos, starcos, westcos My assumption is, that some of the limitations are artificial and effected cards could send/receive more than they do at the moment. But I don't have one of these cards and therefore can't verify it myself. That's why I need your help. If you have one of these cards, then please remove the lines card->max_send_size, card->max_recv_size in the driver and run some tests afterwards. I.e. opensc-tool -f would be fine. Or just write some data objects with: pkcs15-init -W [file] --application-id "1.2.3" --label "MyObject" -a 01 Please include log-files with APDU sequences in your reply. Vendor and Model of reader would be helpful too.
