Action
Pressing BP2 resets the Modem. Hence the equipment
restarts with the parameters in its permanent memory, as
they were configured at the last AT&W command (see § 5
Command mode).
Long pressure on BP1 (> 3s) enables forcing of the serial
link parameters to: RS232, 9600bauds, 8 bits, no parity, no
data rate control. This action will be confirmed by 3 flashes
of the green indicator light.
Brief pressure on PB1 (< 3s) enables restoration of the
serial link default settings (interface self-detection, Auto-
baud, 8 bit data, no parity, no data rate control). This action
will be confirmed by 3 flashes of the green indicator light.
Holding down BP1 (<3s) after having released BP2 triggers
entry into the Command mode. This action will be confir-
med by 3 flashes of the red indicator light.
Holding down BP1 (>3s) after having released BP2 triggers
restarting of the modem with all the default settings (fac-
tory settings). This action will be confirmed by 3 flashes of
the red indicator light.
