AT Commands Structure
Results Code Structure
When a command is issued, the H24 responds with a message, called a "Result Code", which tells
the terminal the result of the command that was requested. Result codes can indicate, for
example, the execution status of the command or the remote modem connection status.
Result codes can be represented either as numerical codes or as verbose responses. By default, the
H24 responds with verbose response codes.
The result code has the following structure:
Prefix Code Suffix
where:
The results code prefix is .
The results code suffix is .
Response and Indications Structure
The following is the information response and indications structure:
Token Separator Arguments
where:
The separator is ":".
The following is an example of Response and Results code:
Information Response to + CMD2=? Also string type subparameters possible
Information Response to + CMD2?
+CMD2: 3,0,15,"GSM"
+CMD2: (0-3),(0,1),(0-12,15),("GSM","IRA")
OK
Final result code
Shows acceptable ranges of each subparameter
Figure 2-3: Response to a Command Line
If verbose responses are enabled (using the command V1) and all the commands in a command
line have been performed successfully, the result code OK is sent from
the H24 to the terminal. If numeric responses are enabled (using the command V0), the result
code 0 is sent instead.
If verbose responses are enabled (using the command V1) and sub-parameter values of a
command are not accepted by the H24 (or if the command itself is invalid or cannot be performed
for any reason), the result code ERROR is sent to the terminal and no
subsequent commands in the command line are processed. If the numeric responses are enabled
(using the command V0), the result code 4 is sent instead. The ERROR (or 4) response may
be replaced by +CME ERROR: when the command was not processed due to an error
related to H24 operation.
