vsmartcard.git contains an implementation of a virtual card reader
(vpcd) which registers with PC/SC (such as pcsc-lite). It simply
binds to a TCP port and waits for a TCP client to connect to it,
implementing APDU transfer over TCP.
This code implements the related protocol as a TTCN-3 test port
for Eclipse TITAN, which will enable us to implement a 'virtual smart
card' in TTCN-3 tets cases, primarily for testing remsim-bankd at
this point.
