|
||
* ------- 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.
