I can't see any way of directly "activating" the AUX bands via CAT ... I was a bit too optimistic.
I'll wait until I crack open the FT-980 again to tap those lines ... perhaps combine a few projects together (TXCO, etc).
What I will do is drop the latest ft980 backend files in (just accepted by the github master), as well as a test file called "ft-980_test.c". Instructions to compile are in the top of the file (make file not required), but you need to put it into "Hamlib\tests" directory to compile to avoid having to add some paths.
This file was designed as a test-vector, to automate the ft-980 backend testing a bit. It should be easy to modify to do whatever you want ;) I will actually be doing a version to optimze the serial timing parameters (running lots of loops and playing with the parameters).
