Bytes are accumulated in an internal buffer; complete CR/LF terminated records are tokenised on demand by nextSample. Token-count heuristics auto-detect the seven- field Euler record (used by FastSCAN-firmware devices) and the eight-field quaternion record (Fastrak with the O,7 output command active), so the same parser drives both generations of hardware. Positions are normalised to SI metres on the fly so downstream coregistration code never needs to know which physical units the device reports.
