Configuring the Unit
If the 1-Character Response option is in effect, unrecognized command strings that are
otherwise formatted correctly will be responded to with OK and no further action will be
taken.
When an active connection is in effect, the unit will be transferring data and will not process
commands received from the serial interface.
When a connection is terminated or lost, the unit will revert to command mode.
When an active connection is in effect, the unit will terminate the connection if the following
sequence is received from the attached serial device:
1. No serial data is received for one second.
2. The character se++ is received, with no more than one second between each
two characters.
3. No serial data is received for one second after the last + character. At this time the unit
will respond affirmatively per the selected echo/response mode.
4. The character string
ATH
is received, terminated with a carriage return. The unit will
respond affirmatively per the selected echo/response mode and drop the network
connection. The serial interface will revert to accepting command strings.
If the above sequence is not followed as described, the unit will remain in data transfer
mode.
