12 // There are three basic operation modes, depending on which device (proxmark/pc)
13 // the signal processing, (de)modulation, transmission protocol and logic is done.
14 // Mode 1:
15 // All steps are done on the proxmark, the output of the commands is returned via
16 // USB-debug-print commands.
17 // Mode 2:
18 // The protocol is done on the PC, passing only Iso15693 data frames via USB. This
19 // allows direct communication with a tag on command level
20 // Mode 3:
21 // The proxmark just samples the antenna and passes this "analog" data via USB to
22 // the client. Signal Processing & decoding is done on the pc. This is the slowest
23 // variant, but offers the possibility to analyze the waveforms directly.
