When I operate CW on my Apache labs SDR rig, Log4OM would not recognize the CWU or CWL modes. I am using TCI interface in Thetis and Log4OM.
The fix is in Thetis, go to Setup,Serial/Network/Midi CAT; click network. Then under TCI Server, check the box for 'CWL/CWU becomes CW (out)'. Log4OM now recognizes the CW mode output from Thetis.
