If the reader doesn't implicitely support auto T0/T1 detection the ctapi driver
will need to detect this from the Atr. ( Mine doesn't do this yet but could
easily ) Up higher in the resource manager we will be using Atr in yet another
configuration file which will contain cards and their functions. ( This will
be done after the initial releases )
BTW - Does anyone here know CORBA ?
Thanks
