Escape to Command Mode
The modem can be moved into command mode in one of two ways: sending the
sequence (pause, +++, pause) to the serial port, or dropping the DTR signal
(AT&Dn).
The first method, sending an escape sequence, moves the modem into command
mode but keeps the connection active. The default escape character is “+” and is
stored in register S2. The default pause value is the value of register S12 (20)
multiplied by 20ms. You can change the defaults by setting the registers with
your own values.
+Bn FALLBACK HOST
Enables or disables switchover to a fallback
host in case of primary host connection fail-
ure.
An ATD command always attempts a connec-
tion with the Remote IP (primary host). If
FallBack IP is configured and enabled, upon
failure to connect with the Remote IP the next
ATD command attempts a connection with the
Fallback IP. Regardless of whether a connec-
tion is established, the next ATD command re-
attempts a connection to the Remote IP.
n=0 Disables switchover to fall-
back host.
n=1 Enables switchover to fall-
back host.
+Hn NETWORK CONTROL
NOTE: For IP232 and Cell 232Plus only.
Establishes or drops PPP connections to the
configured host.
n = 0 (or no option present) Termi-
nates PPP connection
n = 1 Establishes PPP connection
