2.7.3 +<name>: <compound_value>Information Text Formats for Test Commands
In general, the format of information text returned by extended syntax commands is described in the definition of the
command.
The modem may insert intermediate <CR> characters in very long information text responses in order to avoid overrunning
DTE receive buffers. If intermediate <CR> characters are included, the modem does not include the character sequences "0
<CR>"or "OK<CR>", so that DTE can avoid false detection of the end of these information text responses.
2.7.3.1 Range of Values
When the action accepts a single numeric subparameter, or the parameter accepts only one numeric value, the set of
supported values may be presented in the information text as an ordered list of values. The list is preceded by a left
parenthesis (() , and is followed by a right parenthesis ()). If only a single value is supported, it appears between the
parentheses. If more than one value is supported, then the values may be listed individually, separated by comma characters,
or, when a continuous range of values is supported, by the first value in the range, followed by a hyphen character (-),
followed by the last value in the range. The specification of single values and ranges of values may be intermixed within a
single information text. In all cases, the supported values are indicated in ascending order.
For example, the following are some examples of value range indications:
(0) Only the value 0 is supported.
(1,2,3) The values 1, 2, and 3 are supported.
(1-3) The values 1 through 3 are supported.
(0,4,5,6,9,11,12) The several listed values are supported.
(0,4-6,9,11-12) An alternative expression of the above list.
2.7.3.2 Compound Range of Values
When the action accepts more than one subparameter, or the parameter accepts more than one value, the set of supported
values is presented as a list of the parenthetically-enclosed value range strings described above, separated by commas. For
example, the information text in response to testing an action that accepts three subparameters, and supports various ranges
for each of them, could appear as follows:
(0),(1-3),(0,4-6,9,11-12)
This indicates that the first subparameter accepts only the value 0, the second accepts any value from 1 through 3 inclusive,
and the third subparameter accepts any of the values 0, 4, 5, 6, 9, 11, or 12.
