okay, then potentially the Telesec CardManager.NET only uses the TCOS 3.
How can I find out?
(Should we take that conversation to gnupg-devel@?)

Am I understand you correctly that adding the right appversion to the patch
would help? (As your hack is already in GnuPG 2.5.17 which is what I've 
tried.)

 
What is an easy way to find out about the appversion?
(I do not have mich experience with the card development. Is that the "
Detected NKS version: 125" in the log I've send?)

Cool, thanks!
