PIONEERPOS G24-LC manual Results Code Structure, Response and Indications Structure

AT Commands Structure

Results Code Structure

When a command is issued, the G24-L 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 G24-L responds with verbose response codes.

The result code has the following structure:.

Prefix

Code

Suffix

where:

The results code prefix is <CR><LF>.

The results code suffix is <CR><LF>.

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?

<CR><LF>+CMD2: 3,0,15,"GSM"<CR><LF> <CR><LF>+CMD2: (0-3),(0,1),(0-12,15),("GSM","IRA")<CR><LF> <CR><LF>OK<CR><LF>

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 <CR><LF>OK<CR><LF> is sent from the G24-L to the terminal. If numeric responses are enabled (using the command V0), the result code 0<CR> is sent instead.

If verbose responses are enabled (using the command V1) and sub-parameter values of a command are not accepted by the G24-L (or if the command itself is invalid or cannot be performed for any reason), the result code <CR><LF>ERROR<CR><LF> 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<CR> is sent instead. The ERROR (or 4) response may be replaced by +CME ERROR: <err> when the command was not processed due to an error related to G24-L operation.
