I changed it to output  

  $ gpg --card-status --status-fd 2 --batch --no-use-agent
  gpg: pcsc_establish_context failed: no service (0x8010001d)
  gpg: card reader not available
  gpg: OpenPGP card not available: general error
with no reader attached and to 

  gpg: apdu_send_simple(0) failed: no card
  gpg: selecting openpgp failed: no card
  gpg: OpenPGP card not available: general error
if a reader is attached but no card inserted.

    CARDCTRL <what> [<serialno>]
        This is used to control smartcard operations.
        Defined values for WHAT are:
           1 = Request insertion of a card.  Serialnumber may be given
               to request a specific card.
           2 = Request removal of a card.
           3 = Card with serialnumber detected
           4 = No card available.
           5 = No card reader available
