example of a reader.control function

[barisvelioglu]

I am using ACR1252U-A1 for reader. I cannot do any transmit operations succesffully but I cannot get any response by using control command.

What I tried is

reader.control(new Buffer([0xE0, 0x00, 0x00, 0x18, 0x00]), 3500, 30, function(err, data)[
  console.log(data) // undefined
});

Control code should be set based on your OS.

So instead of directly using 3500 set it with reader.SCARD_CTL_CODE(3500)

reader.control(new Buffer([0xE0, 0x00, 0x00, 0x18, 0x00]), reader.SCARD_CTL_CODE(3500), 30, function(err, data)[
  console.log(data) // undefined
});

That works like a charm. Thank you!
