Received commands must begin with the two-character sequence AT and be terminat ed 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 c ompound AT commands as unrecognized
commands.
If the Full Verbose option is in effect, the unit responds to an unrecognized comm and 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 unrec ognized command
string that is otherwise formatted correctly with the "OK" message and takes no further action.
When an active connection is in effect, the unit transfers data and does n ot process commands
received from the serial interface.
When a connection is terminated or lost, the unit reverts to comm and mode.

characters.
No serial data is received for one second after the last + character. At th is time, the unit
responds affirmatively per the selected echo/response mode.
The character string ATH is received, term inated 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 m ode.
