I have tried two different interfaces using optoisolators to attempt FSK and PTT keying from a serial card to the rear panel ACC2 connector.

I used an interface very similar to this one (http://www.w3yy.com/fsk.htm) for a few years with my Icom IC-7600. It worked very well when driven by a real RS-232 COM port on a desktop computer. I can't tell you the optoisolator part numbers, but it worked very well for me.
