I came across this schematic using FT232RL usb to TTL converter. The link is here http://conture.by/post/1228
I made this at home. I am getting proper response after pcsc_scan. But when any code involves trasmit, then it fails to transmit. As a sim card reader it is working fine. Is there any tweaking to be done like active high or low reset ? All i am trying to make a small interface using open hardware and open software.
