Response/Action
OK
The set command defines the behavior
mode of each selected IO pin.
or:
The G24 saves the new setting in flex.
+CME ERROR: <err>
The selected pins are affected. Validity
check of all parameters will be done
and appropriate standard error will be
issued.
In case of legal parameters the new
configuration is set. If <Data vector>
doesn't supply and new <Mode> is
output a line will care physical high
signal. In case <Data vector> is supply
and includes values of input pins, those
values will be ignored. In case
<Mode> is input and <Data vector> is
supply, an error will be issued
"Operation not allowed". No action
will be done.
+MIOD: <Mode vector>
The read command returns the current
behavior mode of the 8 GPIO pins.
