Not Subject to NDA

AT commands serial port mode: the V24 pins are

controlled by the serial port device driver

GPIO mode: output pins can be managed through the

AT#V24 command only

GPIO Kernel mode: output pins directly controlled by

kernel GPIO driver

<save>

integer

N/A

Save V24 pin configuration

Values:

Pin configuration is not saved

Pin configuration is saved

If <mode> is set to 2, output pins directly can't be controlled by

#V24 command, <save> parameter should be set to 1, module

must be reboot, the pins configuration is applied next power cycle

and pins directly controlled by kernel GPIO driver.

If <save> parameter is omitted, the value of <mode> is changed as

default mode from next power cycle.

Changing V24 pins configuration may affect the cellular module

functionality set through +CFUN.

If <pin>=4 is set to <mode>=2 or 1, <save> parameter should be set

to 1, module must be reboot, pin configuration is applied next

power cycle. Changing from <mode>=2 or 1 to <mode>=0, module

must be reboot.

If <pin>=1, 5 ,6 or 7 is set to <mode>=2 or 1, <save> parameter

should be set to 1, module must be reboot, pin configuration is

applied next power cycle. The unset pins of 4 pins don't work as

UART pin. Changing from <mode>=2 or 1 to <mode>=0, module

must be reboot.
