! U1 S-CARD CT_ATR
Response:
<ACK><LENGTH><ATR DATA>
CT_DATA: This command is used to send a command to the smart card. The response from the card
is returned. A command of this type has the following form:
<CT_DATA> <Length of command> <card command in ascii form>
CT_DATA Example :
! U1 S-CARD CT_DATA 10 8010000008
Description: CT_DATA: indicates the command is to go to the smart card.
10 = length of command
8010000008 = Command to go to the card in ASCII form. This command is converted to
binary and sent to the card.
CT_CLOSE: This command will power down the reader and turn off the red LED on the smart card
module. (LED is available with Cameo “SC” models only). This command should be used after
communicating to the card with the CT_DATA command.
CT_QUERY: This command is used to retrieve any buffered card response. It is to be used after
issuing a card command with the ‘QUERY’ option. This command is only available with the TDA8029
and SCR135 readers.
DEBUG-ON: Enables debug on the printer. This will cause some messages to print out as the printer
configures itself for pass-through mode. The messages printed relate to port parameters for the
internal communication port communicating with the Smartcard reader and a message will also print
out when the printer has been taken out of pass-through mode. Once in ‘pass-through’ mode, no
debug messages are printed.
{Options}
Note: {Options} must precede the {Operation}
ASCII: Data returned from the card will be converted to ASCII. Normally, data returned is in binary
form. However, with the ASCII option, returned data will be in ASCII form.
