SW: MPManager (all version)

Issue Details

There is a Spy feature button in MPManager : 

Does this feature allow me to sniff or capture the communication between an external reader and a smartcard?


Depending on the kind of device you are using, you can capture the communication 
between a DUT and the tester involved in the communication - internal spy -
or between an external reader and a smartcard - external spy.

Protocol analyzers such as MP300 SC2, MP300 ACL1 and MP007 are sniffers made to capture the communication between two devices.

Testers like MP300 TC3, MP500 TCL3 and MP500 PT1NFC are able to capture the communication in which one they are involved. 

Independently from the kind of device used, the user can start to spy a communication when using MPManager features:
- the "Spy" button on top of the MPManager user interface
- a "Start spy" and "Stop spy" commands inserted within a Script in MPManager script editor:
