ALT12: TGPIO_03 goes low when there is a CS or a PS attach, even
in ROAMING, otherwise it is high.
ALT14: GPIO_04 goes low as soon as a TX packet (PPP, ECM) is
sent, and then it starts toggling high and low with 100 ms time as
long as TX packets are sent. When there are no more packets to
sent the pin goes back to high state.
ALT15: GPIO_05 goes low as soon as a RX packet (PPP, ECM) is
received, and then it starts toggling high and low with 100 ms time
as long as RX packets are received. When there are no more
packets to receive the pin goes back to high state.
While using the pins in the alternate function, the GPIO read/write
access to that pin is not accessible and must be avoided.
AT#GPIO?
Read command reports, for any GPIO pin, a row showing the current
parameters values. Row one shows GPIO pin one, row two shows GPIO pin
two, and so on.
#GPIO: <dir>,<stat><CR><LF>
#GPIO: <dir>,<stat><CR><LF>
...
If GPIO was previously set to <mode>= 3 or 4, the format of the returned
message is:
#GPIO:<dir>,<stat>,<mode><CR><LF>
#GPIO:<dir>,<stat>,<mode><CR><LF>
...
AT#GPIO=?
Test command reports the supported range of values of the command
parameters <pin>, <mode>, <dir>, and <save>.
