-/*
- * The packet format is a simple hex dump of the raw telemetry frame.
- * It starts with 'TELEM', then contains hex digits with a checksum as the last
- * byte on the line.
- *
- * Version 4 is a replacement with consistent syntax. Each telemetry line
- * contains a sequence of space-separated names and values, the values are
- * either integers or strings. The names are all unique. All values are
- * optional
- *
- * VERSION 4 c KD7SQG n 236 f 18 r -25 s pad t 513 r_a 15756 r_b 26444 r_t 20944

- * General header fields

- * Name Value

- * VERSION Telemetry version number (4 or more). Must be first.
- * c Callsign (string, no spaces allowed)
- * n Flight unit serial number (integer)
- * f Flight number (integer)
- * r Packet RSSI value (integer)
- * s Flight computer state (string, no spaces allowed)
- * t Flight computer clock (integer in centiseconds)
- *
- * Version 3 is Version 2 with fixed RSSI numbers -- the radio reports
- * in 1/2dB increments while this protocol provides only integers. So,
- * the syntax didn't change just the interpretation of the RSSI
- * values.
- *
- * Version 2 of the telemetry data stream is a bit of a mess, with no
- * consistent formatting. In particular, the GPS data is formatted for
- * viewing instead of parsing. However, the key feature is that every
- * telemetry line contains all of the information necessary to
- * describe the current rocket state, including the calibration values
- * for accelerometer and barometer.
