Thanks for the private e-mails, the CI-V is now working.  too my
surprise invoking grig or rigctld would not work until I dropped the
CI-V address in the command line.  Without -c14 (or -c anything) it
worked.  I have more questions, now that I can follow the Doppler
shift, in a subsequent post.

Going to try in a minute or two on XW-2
