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?

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.

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
