Re: [CAD_CAM_EDM_DRO] Re: Keyboard Typematic rate

Have been watching this thread and I don't know much
about programing, but I just installed EMC along with red hat linux 6.2 and
noticed in a input device window in the KDE desktop that lets you disable
typmatic rate, You
might want to see how they do it.
