9455b51c 13// There are three basic operation modes, depending on which device (proxmark/pc)
14// the signal processing, (de)modulation, transmission protocol and logic is done.
15// Mode 1:
16// All steps are done on the proxmark, the output of the commands is returned via
17// USB-debug-print commands.
18// Mode 2:
19// The protocol is done on the PC, passing only Iso15693 data frames via USB. This
20// allows direct communication with a tag on command level
21// Mode 3:
22// The proxmark just samples the antenna and passes this "analog" data via USB to
23// the client. Signal Processing & decoding is done on the pc. This is the slowest
24// variant, but offers the possibility to analyze the waveforms directly.
