Error

Received commands must begin with the two-character sequence AT and be terminated with a carriage return character.

The unit ignores any character sequence received not starting with AT, and only recognizes and processes single AT-style commands. The unit treats compound AT commands as unrecognized commands.

If the Full Verbose option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly (begins with AT and ends with carriage return) with the "OK" message and takes no further action.

If the Numeric Response option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly with a "0" message and takes no further action.

When an active connection is in effect, the unit transfers data and does not process commands received from the serial interface.

When a connection is terminated or lost, the unit reverts to command mode.

When an active connection is in effect, the unit terminates the connection if it receives the following sequence from the attached serial device:

No serial data is received for one second.

The character sequence +++ is received, with no more than one second between each two characters.

No serial data is received for one second after the last + character. At this time, the unit responds affirmatively per the selected echo/response mode.

The character string ATH is received terminated with a carriage return. The unit responds affirmatively according to the selected echo/response mode and drops the network connection. The serial interface reverts to accepting command strings.

If this sequence is not followed, the unit remains in data transfer mode.
