M581 in RRF3

[chas2706]

I have set up an external trigger to execute an e-stop on button press.
This is giving me two problems:

1. When enabled in config.g I get random e-stop occurrences. ( I have a normally open switch connected to gnd and in on io2.in).

2. In the documentation for M581 it says:

"When M581 is executed, if the T parameter is present but the other parameters are omitted, the trigger inputs and edge polarities for that trigger number are reported. "

Here is my config for M581:

M581 P"^!io2.in" T0 C0 ; configure active-low endstop to perform an e-stop and let it trigger at any time without restrictions

When I enter M581 T0 in the console I get this :

If I disable the M581 command in config.g I can print without problems,
BTW my endstops are configured and wired in the same way without issues.
