If you want to confirm the interface is working you might try using SATPC32.  I seem to recall helping the developer test some functionality on my FT736 approx 10 years ago.  It worked well for me when I used to work satellites.

I wrote a program on an old CP/M system back in 1983 when I got my FT736 but without polling, it's not very useful. Most modern software doesn't support the rig either. The only items you can poll is the s-meter (pretty useless) and the status of the squelch (almost as useless!!). You could also set up the duplex for crossband operation. The radio came with the CAT interface but it's a DIN connector and operates at TTL levels so you need to use a MAX232 or similar chip to get RS232 levels. I think Yaesu's incarnation was a FIF-232 but the Kenwoood unit for a TS850 worked with the correct pinout on the DIN.
