Hello ! I understand that CAT is not yet fully ready.
When I use latest "VarAC_cat_commands.ini" with ft847 the 847 appears in PTT (still PTT doesn't work) but not in Frequency control (so also doesn't work).
With both OmniRig PTT and Frequency are working, but I must kill Omnirig (Task Manager) to get the serial com port free when I end with varAC - OmniRig usually doesn't close with closing varAC.
CAT would be nicer then Omnirig to avoid this process-killing-issue.
