8.7.2Interface 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.
