7: Setup Mode: Channel Configuration

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.
