Parameters
HwGpioNum – I/O port number (1–8)
HwGpioState – I/O port state – See note below

Notes
GPIO-STATE? can only be sent in digital mode and the answer is 0=Low, 1=High. In analog mode an error
message is sent.
GPIO-STATE can only be sent in digital out mode and the parameter is 0=Low, 1=High. In all other modes
an error message is sent.
The device uses this command to notify the user of whenever there is a change regarding the state.
Example
Set state for digital I/O port number 1 to high:
#GPIO-STATE 1,1<CR>
