Hello Werner,

I finally found the time to test the latest version of gpg2 (incl. your

I noticed an important difference between gpg 1.4.9 and 2.0.12: when I
have the wrong card inserted (e.g. for decryption), gpg 1.4.9 responds
with these status messages:

[GNUPG:] ENC_TO 12A7990DF2541241 1 0
[GNUPG:] CARDCTRL 3 D2760001240101010001000000460000
