New Message Acknowledgement +CNMA

Description: This command allows reception of a new message routed directly to the TE to be acknowledged.

In TEXT mode, only positive acknowledgement to the network (RP-ACK) is possible.

Acknowledge with +CNMA is possible only when a +CMT or +CDS indication is shown (see +CNMI command).

Note: This AT command is not designed for input of the command into the Hyper terminal by hand since the acknowledgement will not be quick enough to be received by the network. However, it is possible for the client system to automatically send this command when the +CNMI is set to “2,2,0,0,0”.
