*
* ------- 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.
*

*
* This function takes a character buffer that has been received as a report

* 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.
