Connection status

<text> output only if ATX parameter setting with value greater 0.

Notes

•Any additional commands on the same command line are ignored.

•The command may be aborted generally by receiving a character during execution. It can't be aborted in some connection setup states, such as handshaking.

•If AT+FCLASS setting is 1 or 2, all incoming calls will be answered as fax calls, when ATA is issued on multi- plexer channel 1 resp. ASC0. For calls explicitly signalled as voice or data calls, this procedure will fail with result code "NO CARRIER", but the call in question will continue to ring.

It is possible to change the setting for AT+FCLASS to 0 while the call is ringing, and accept the call normally afterwards with ATA.

•The ATA command may be used also to accept a network request for a PDP context activation (see ATA).

•See also ATX for <text>.

•If an incoming call is no longer available (already disconnected/hanged up)a "NO CARRIER" result code will be given.
