Program recomendations for fanuc drip feed/program input/output

Hi

I wonder what program you guys recommend for be able to drip feed a fanuc,i want to use "Ethernet" for this if possible, controller has Focas aswell.

I have several older fanuc controllers, have an old 9X pc? they handle serial ports much better. Then a simple bitcom or similar freebie. Low speed bauds switches everywhere, works fine. search: rs232 null modem cable pinouts. dont get overwehlmed, its easy.
