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 the "OK" 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 se++ 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.
