Thank you Chris. Sometimes these little bits of information make all the difference. I did not get this searching linuxcnc.org so either, I did not search well enough, or I need to put the information on the wiki somewhere. I hope to be able to document the whole HNC conversion in a month or two, so that the next person will have an easier go of it.
I just went back and did a search for iocontrol.0.tool and found: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMCMOT_And_EMCIO_HAL_Interface ,so it is documented. I now remember reading this page a while back, but it had no meaning at the time. Now that I have used HAL a little it is making more sense. (It is plainly in the Integrator,s Manual too. I need to reread the manuals.)
