8.7.2 Interface Description
This command replies to the ^HCMT or ^HCDS indication received by the TE from
the MT.
The execution command acknowledges the reception of a new short message sent
to the TE. For usage of the command, see the +CNMI command.
Before the previous received short message is acknowledged, the MT does not send
another ^HCMT or ^HCDS command to the TE.
If the MT does not obtain a short message acknowledgement in the specified time
(about two seconds) (due to network timeout), it sends "RP-ERROR" to the network.
If this command is executed but no short message needs to be acknowledged,
"+CMS ERROR:<err>" is returned.
