 *
 * -------  BYTE-SWAPPING  -------
 * TSIP is big-endian (Motorola) protocol.  To use on little-endian (Intel)
 * systems, the bytes of all multi-byte types (shorts, floats, doubles, etc.)
 * must be reversed.  This is controlled by the MACRO BYTESWAP; if defined, it
 * assumes little-endian protocol.
 * --------------------------------
 *
 * T_PARSER.C and T_PARSER.H contains primitive functions that interpret
 * reports received from the receiver.  A second source file pair,
 * T_FORMAT.C and T_FORMAT.H, contin the matching TSIP command formatters.
 *
 * The module is in very portable, basic C language.  It can be used as is, or
 * with minimal changes if a TSIP communications application is needed separate
 * from TSIPCHAT. The construction of most argument lists avoid the use of
 * structures, but the developer is encouraged to reconstruct them using such
 * definitions to meet project requirements.  Declarations of T_PARSER.C
 * functions are included in T_PARSER.H to provide prototyping definitions.
 *
 * There are two types of functions: a serial input processing routine,
 *                            tsip_input_proc()
 * which assembles incoming bytes into a TSIPPKT structure, and the
 * report parsers, rpt_0x??().
 *
 * 1) The function tsip_input_proc() accumulates bytes from the receiver,
 * strips control bytes (DLE), and checks if the report end sequence (DLE ETX)
 * has been received.  rpt.status is defined as TSIP_PARSED_FULL (== 1)
 * if a complete packet is available.
 *
 * 2) The functions rpt_0x??() are report string interpreters patterned after
 * the document called "Trimble Standard Interface Protocol".  It should be
 * noted that if the report buffer is sent into the receiver with the wrong
 * length (byte count), the rpt_0x??() returns the Boolean equivalence for
 * TRUE.

 * T_REPORT.C consists of a primary function TranslateTSIPReportToText()
 * called by main().
 *
 * This function takes a character buffer that has been received as a report
 * from a TSIP device and interprets it.  The character buffer has been
 * assembled using tsip_input_proc() in T_PARSER.C.
 *
 * A large case statement directs processing to one of many mid-level
 * functions.  The mid-level functions specific to the current report
 * code passes the report buffer to the appropriate report decoder
 * rpt_0x?? () in T_PARSER.C, which converts the byte stream in rpt.buf
 * to data values approporaite for use.
