Hi Robert, I'm not sure on the CT-16 or equivalent, but I do have a couple of circuits I can share with you that will provide CI-V control from your PC. I have not built any of these, but they look fairly straightforward:

I think you can use the MAX232 or two transistor interface.

I've also attached a schematic for another interface that someone else shared with me as well.

I'd be curious to know if anyone is using two 706's autonomously with PC control for sat work. I would also think you may be able to take two of the aforementioned circuits or equivalent and be able to accomplish the same thing?

Hope that helps.

I used a CT-16 with a pair of IC-706's to operate AO-40 on the TZ6RD trip.

It works pretty well, although the 1200 baud speed introduces more latency then is really comfortable. Obviously, doing this with a more capable computer that would take care of Doppler too would be better. And a higher speed unit would be good, but no one has done that, to my knowledge. I think this would be easy to implement in a PIC, but what do I know?

A combination unit, with a USB interface that looked like either one or two serial interfaces to a connected computer, and could function stand-alone like a CT-16 would be ideal, and substitute for a CT-17, too.

Being able to change the configuration with push-push switches is actually very nice and user-friendly, in my view, BTW.

BTW, a CT-16 doesn't require a CT-17 to operate. I always disconnected the one to hook up the other, since I was also using one of the IC-706's for HF operation, with a logging program hookup.
