Roger,

just tested with a MK1. The tuner . and ; commands don't appear to do anything (I stay on the same frequency I am on), but if I am tuned to a preset (A4 for example) then issuing either of those commands appears to move it off preset (only A displayed) but the frequency displayed doesn't change. I only tested on FM, I can retest on AM if it helps.

I also tried all the other commands (except the misc ones) and they all work with the exception of loudness up. loudness down works fine though.

Tests done with V2.00Final, no HiJack
