CAT Frustration for ICOM-IC-706MK2g

I am having difficulty with the CAT for my Laptop running WSJTX for FT8 and the logger Log4OM NextGen, and OmniRig middleware to control the xmit and radio frequencies. No CAT to WSJTX, nor Log4OMNextGen. This is a new DigiRig purchased with corresponding ICOM cables.
I don’t find how to update the parity and stop bits DTS,RTS levels in the radio to validate these settings.
This is the set up I use with a desktop, into my IC-765PROII, but with no luck
Any help will be appreciated.
