//-----------------------------------------------------------------------------
+// The ISO 15693 describes two transmission modes from reader to tag, and 4
+// transmission modes from tag to reader. As of Mar 2010 this code only
+// supports one of each: "1of4" mode from reader to tag, and the highspeed
+// variant with one subcarrier from card to reader.
+// As long, as the card fully support ISO 15693 this is no problem, since the
+// reader chooses both data rates, but some non-standard tags do not. Further for
+// the simulation to work, we will need to support all data rates.
+//
+// VCD (reader) -> VICC (tag)
+// 1 out of 256:
+// data rate: 1,66 kbit/s (fc/8192)
+// used for long range
+// 1 out of 4:
+// data rate: 26,48 kbit/s (fc/512)
+// used for short range, high speed
+//
+// VICC (tag) -> VCD (reader)
+// Modulation:
+// ASK / one subcarrier (423,75 khz)
+// FSK / two subcarriers (423,75 khz && 484,28 khz)
+// Data Rates / Modes:
+// low ASK: 6,62 kbit/s
+// low FSK: 6.67 kbit/s
+// high ASK: 26,48 kbit/s
+// high FSK: 26,69 kbit/s
+//-----------------------------------------------------------------------------
+// added "1 out of 256" mode (for VCD->PICC) - atrox 20100911
+
+
+// Random Remarks:
+// *) UID is always used "transmission order" (LSB), which is reverse to display order
+
+// TODO / BUGS / ISSUES:
+// *) writing to tags takes longer: we miss the answer from the tag in most cases
+// -> tweak the read-timeout times
+// *) signal decoding from the card is still a bit shaky.
+// *) signal decoding is unable to detect collissions.
+// *) add anti-collission support for inventory-commands
+// *) sniffing and simulation do only support one transmission mode. need to support
+// all 8 transmission combinations
+// *) remove or refactor code under "depricated"
+// *) document all the functions

+// Mode 2:
+// The protocol is done on the PC, passing only Iso15693 data frames via USB. This
