Since my last post, I have setup FLRig and tested using that with all of the software I normally use and have found it to work well. I have switched to using that and with today's release of VarAC, I tried it with that and everything is working just fine. So this feature request is no longer needed, at least for me.

I don't use FLRIG for anything currently. I do have it and FLDigi installed but I don't use them for anything at the moment. I use OmniRig in everything else.

Selecting Omni-Rig for PTT doesn't work. I assume that doesn't work because the IC-718 doesn't support PTT through the CI-V control. It doesn't work in WSJT-X either. I was able to just get everything working by not using Omni-Rig and setting everything up direct: I don't necessarily need Omni-Rig. I can manually log everything in Log4OM. I will just need to be careful with making sure everything is turned off before opening VarAC. I appreciate you trying to work through this with me.

Yep, it's working. Here are my Omni-Rig settings. Also, as a test, in WSJT-X, I selected COM8 instead of CAT for port, and that does not work. If I click Test PTT, nothing happens. So I suspect that this CAT setting is actually something that tells Omni-Rig to do this instead of opening that port up and doing it.

I was just in js8call, which has the same setup as wsjt-x, and I hovered over that drop down for PTT method port and noticed the message that CAT may be a special value that might need to be used instead of serial port...

Here are the settings for WSJT-X that work. If I click on Test PTT, it keys up the rig. In VarAC, here is what I have set up. For DTR/RTS port, there is just my COM1, COM5, and COM8, COM8 is what the rig is connected to. If I click TEST PTT ON, I get the error shown in the CAT Test Error Log area.
