Some of them like mc.OSIG_OUTPUT2, mc.OSIG_OUTPUT3, etc. are easy, but others like the output for Soft Limits are not so intuitive.  Is there a list of inputs and outputs? 

Thanks

Look in the Mach4Hobby docs directory at the Mach4CoreAPI.chm and look in the section for Signals.

Thanks.  I remembered seeing the list but thought it was in another document.
