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.
