most cards and readers on the market don't support APDUs bigger than 256 bytes.
As far as I know my card and reader should support the extended length commands. As mentioned above, i'm able to receive more than 256 bytes via JCShell.
This is most likely a problem with GPShell. It has been around for a while and I haven't noticed much active development so it may not have added support for extended length apdu's. You could always send the commands with Java using javax.smartcardio.*.
thank you for your hint.
smartcardio API is very comfortable tool. now I'm able to return up to 8190B otherwise error in my new thread :)
