Sorry, I don't understand your question.  scdaemon is managed by
gpg-agent and started as needed.  You could use scdaemon on your own but
that is not suggested because it would conflict with gpg-agent's use of

You can use all scdaemon commands via gpg-agent by prefixing the command
with "SCD ", like this

  $ gpg-connect-agent 
  > scd apdu --atr
  S CARD-ATR 3BDA11FF81B1FE551F0300318473800180009000E4



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
