|
|
|
20 |
* - Each of the AT commands sent to ATEXT are converted to upper case form.
|
|
|
21 |
* Thus the ATEXT plugins don't need to check for case. The conversion to
|
|
|
22 |
* upper case form stops when carriage return or '=' character is found.

* This file has the following functionality:
|
|
|
27 |
* 1) Line buffer filler:
|
|
|
28 |
* AddDataForParsing(), ManagePartialCommand(), ExtractLineFromInputBuffer(),
|
|
|
29 |
* etc. This buffer is used for parsing. These functions are used for
|
|
|
30 |
* splitter-combiner logic described below. CDunAtCmdPusher is used
|
|
|
31 |
* separately for each element in the line buffer.
|
|
|
32 |
* 2) Parser and splitter-combiner to handle the separater elements (subcommands)
|
|
|
33 |
* in the line buffer. When end of line is detected, iEndIndex is used to
|
|
|
34 |
* extract the next line in iInput to the line buffer (ManageEndOfCmdHandling()
|
|
|
35 |
* and ExtractLineFromInputBuffer()).
|
|
|
36 |
* 3) When end of iEndIndex is found (ExtractLineFromInputBuffer()), more data
|
|
|
37 |
* is asked from CDunUpstream.
|
|
|
38 |
* Note: There is separate handling for "one character input data" and "A/"
|
|
|
39 |
* command handling which should be supported only for one line based data
|
|
|
40 |
* (ManagePartialCommand()).
|

/*

* The AT command handling is splitted to two parts on high level:
|
|
|
45 |
* 1) Splitter: splitting the sub-commands in a command line to multiple ones
|
|
|
46 |
* for ATEXT to process.
|
|
|
47 |
* 2) Combiner: combining the replies coming from ATEXT using a filter
|
|
|
48 |
* (the filter categories are explained in DunAtCmdPusher.cpp)

/*

52 |
* Note1: This file uses AT command parsing based on heuristics.
|
|
|
53 |
* Refer to test specification if planning to change the heuristic.
|
|
|
54 |
* Note2: Input buffer management (ExtractLineFromInputBuffer()) can be tested
|
|
|
55 |
* with non-line based terminals such as HyperTerminal or Realterm.
|
|
52
|
56 |
* Note3: If there is a need to handle commands with random data, the extended
|
|
|
57 |
* command checking can interfere with the character set of this random data.
|
|
|
58 |
* Best way to handle this random data is to create a handler for these commands
|
|
|
59 |
* which skips the valid "not to be parsed" data or use quotes. For these cases
|
|
|
60 |
* the CDunAtSpecialCmdHandler could be extended.
