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>.
NOTE: The command line buffer accepts a maximum of 80 characters. If this number is
exceeded none of the commands will be executed and TA returns ERROR.
