• +CMD1=?<CR> This is a test command for checking possible subparameter values

These commands might be performed in a single command line as shown below:

ATCMD1 CMD2=10+CMD1;+CMD2=, ,10;+CMD1?;+CMD1=?<CR>

anyway it is always preferable to separate into different command lines the basic commands (i.e. without + prefix) and

the extended commands (the ones with + prefix); furthermore it is suggested to avoid placing several action commands

in the same command line, because if one of them fails, then an error message is received but it is not possible to argue

which one of them has failed the execution.

If command V1 is enabled (verbose responses codes) and all commands in a command line has been performed

successfully, result code <CR><LF>OK<CR><LF> is sent from the TA to the TE, if subparameter values of a

command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason,

result code <CR><LF>ERROR<CR><LF> is sent and no subsequent commands in the command line are processed.

If command V0 is enabled (numeric responses codes), and all commands in a command line has been performed

successfully, result code 0<CR> is sent from the TA to the TE, if sub-parameter values of a command are not accepted

by the TA or command itself is invalid, or command cannot be performed for some reason, result code 4<CR> and no

subsequent commands in the command line are processed.

In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR: <err> or

+CMS ERROR: <err>.
