PioneerPOS G24-LC 用户手册

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:.

where:

The results code prefix is <CR><LF>.

The results code suffix is <CR><LF>.

The following is the information response and indications structure:

where:

The separator is ":".

The following is an example of Response and Results code:

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.
