Is the macro, SCARD_CTL_CODE(code) (0x42000000 + (code)), default macro?
If not, could you please let me know where I can find the default macro
definition?

<key>ifdDriverOptions</key>

        <!-- Possible values for ifdDriverOptions

                the CCID Exchange command is allowed. You can use it
through
                SCardControl(hCard, IOCTL_SMARTCARD_VENDOR_IFD_EXCHANGE,
...)

Is this correct.

Can we use SCardControl with GemPC410 at all. If so how we can make
SCardControl to work with GemPC410 card reader.

>What do you refer to by control codes? What are you tring to do?
I'm sorry for this imprecise information; this terminology is very new
to me as I'm in still in learning stage. Actually, I mean
"SCARD_CTL_CODE".

What is SAM ? Secure Authentication Method ? depends on how the
keyboard implements it.

It is Secure Access Module chip, this will be inserted into one of the 4
slots provided on the back side of the Cherry keyboard.
How can we detect this SAM chip?

Kindly let me know.

Cheers,

Naveen
