Hello!
Current implementation of the method
javax.smartcardio.CardChannel.transmit() has an internal limitation on
the maximum allowed amount of the transmitted data.
This limitation is dictated by the maximum number of iterations to
transmit data from a card: Each iteration can transmit up to 256 bytes
of data, and we have a hardcoded limit of 32 iterations.
Over time, we've received requests to increase this limit, as there are
occasions when the effective limit of 8k is not enough.
Would you please help review a proposal: First, it is proposed to
increase the default limit of iteration to 128 (so that up to 32k of
data can be transmitted); Second, the limit of iterations is made
configurable via a System property. This limit can be increased up to
4096 (so that the total amount of transmitted data can be made up to 1m).

If there is an agreement on the proposal, I'll file a CSR to document a
new System property.
Thanks in advance!
