From d7d218ef02d87c637d20d64da8f575d434ff6f78 Mon Sep 17 00:00:00 2001 From: Alon Levy Date: Wed, 27 Mar 2013 10:14:15 +0200 Subject: dev-smartcard-reader: change default protocol to T=0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We don't support T=1 so we shouldn't advertise it by default. Two independent changes: * Default ATR sets T=0. This gets overwritten by the client provided ATR later. * Class descriptor changes dwAdvertise dwProtocols.PPPP to 0x1 and dwProtocols.RRRR=0 per spec.
