195 data bytes, if any. After executing the APDU exchange, the apdu command simply 195 data bytes, if any. After executing the APDU exchange, the apdu command simply
196 prints the SW response code from the SIM. 196 prints the SW response code from the SIM.

198 A different form of the raw APDU command is provided for use in custom command
199 scripts:
200
201 apdu-checksw "xx xx xx xx xx ..." YYZZ

203 This command takes two arguments at the argv level: the first is the same string
204 of bytes as in the basic apdu command (will need to be quoted if it contains
205 spaces between bytes), and the second argument is the expected SW response from
206 the SIM. If the SW response from the SIM is exactly as expected, the execution
207 of the command is considered to be successful; if the SW response is different,
208 an error is reported and script execution is stopped.
