* src/engine-assuan.c (inquire_cb): Implement returning data. * tests/opassuan/t-command.c (inq_cb): Send some test data. -- The old code only allowed to send an empty response which was good enough for scdaemon's KNOWNCARDP inquire but not to send actual data. A quick test using a test smartcard might be ./t-command 'scd setattr --inquire PRIVATE-DO-1' and then reading the data back using gpg-connect-agent 'scd getattr PRIVATE-DO-1' /bye Signed-off-by: Werner Koch <wk@gnupg.org>
