I notice the same thing.
I also notice that typing ioman alone comes up with:
Arguments failed
Usage: [input (digital1, digital2, analog)] [value (0, 1, volts (0.018))]
OK, so I then type_______________: ioman input digital1
no error, but no data.
so I try _______________: ioman input digital1 {status, value, 0, 1, volts}
they all produce "Arguments failed"
If I omit "input" thinking that is simply a keyword and the actual arguments are digital1, digital2, analog that is also an error
that also raises the question "ioman" implies Input and Output - yet there is no mention of that in the Usage
I think this utility is only 25% done at best, and broken.
So, I think, OK, there is a curl prototype too...
curl -X GET "http://192.168.1.1/cgi-bin/io_value?username=user1&password=user1&pin=dout1"
that returns an error too - whether issued from the CLI or from the PC connected to it
