gpio command: General Purpose Input Output (GPIO)
GPIO commands are necessary to configure a WR44, which has one Digital Input/Output port

gpio

in : OFF
Output(s):
inout : OFF
OK

To set the I/O port to be an output:
gpio inout output
Input(s):
in : OFF
Output(s):
inout : OFF
OK
Set the I/O port to ON when configured as an output
To set the I/O port to
