The MT shall automatically disable routing to the TE by setting both <mt> and <ds> values of +CNMI to zero.
If the command is executed, but no acknowledgement is expected, or some other MT related error occurs, the
final result code +CMS ERROR: <err> is returned.
In PDU mode, it is possible to send either positive (RP-ACK) or negative (RP-ERROR) acknowledgement to the
network. The <n> parameter defines which one will be sent. Optionally (when <length> is greater than zero) an
acknowledgement TPDU (SMS-DELIVER-REPORT for RP-ACK or RP-ERROR) may be sent to the network. The
entering of PDU is done similarly as specified in +CMGS command, except that the format of <ackpdu> is used
instead of <pdu> (i.e. SMSC address field is not present). The PDU shall not be bounded by double quotes.
