I created a Dropbox folder for "work in progress" type material, and uploaded my current hamlib alpha-testing directory. Let me know if you don't receive and email invitation ...
fldigi has a number of different CAT method options built-in supposedly, including hamlib. However, I was unable to get it to connect via hamlib to the FT-980. I'll try again.
flrig appears to be closed-source, which is a potential issue (have to convince the developers to assist if the base code needs to be modified. The rig description files are .xml-based, which helps ... but the FT-980 has a particular quirk that could be a problem. The FT-980 CAT system uses an echo back PLUS an "execute" command, in addition to the command. While a few other rigs seem to have the "echo-back", the "execute" command seems to be unique.
1. PC -> Rig: Command
2. Rig-> PC: Echo-back
3. PC-> Rig: Execute
If the flrig base code doesn't support both the echo-back and execute quirks (so we can just create the .xml file), then we would need the developer support.
But first things first for me: I'm going to concentrate on hamlib (fix bugs, add functionality). What is really intriguing is the rigctlcom program (TS-2000 translator) that might even help workaround fldigi/flrig.
