The problem is the wrong setting of DTR and RTS signals. The Icom and OmniRig must be the same. Set Omnirig RTS High, DTR low- will be fine. Set Icom RTS ....according to the following: USB SEND (Default: OFF) You can control transmit and receive from the PC through the USB port. Selects the control...

Do it is way:
Remove drivers ICOM (Silicone labs)
Restart PC
Instal Driver ICOM ...
Check parametr in TRX baud rate 115 200 , echo ON, etc..
Conect TRX via USB and set parametrs in Log4ON- OmniRig ,com, baud rate ...

But in the statistic and awards is also only Phone, CW, Digital ...

The window where you can see what I have done or confirmed is only 3 groups: Phone, CW, Digital would have to be so that instead of digital set FT8, RTTY, JT65 to be configurable, anyone could set which broadcasts he is interested in.

Which RTTY software can connect with Log4On.
Program types MMRTTY etc ...?
I'm not interested in HRD etc ..

But I checked but unfortunately I had to go back to the old driver because Omnirig was not working, other programs worked fine.

So you're sirting to change the Icom driver to the one you're linking to?

So you had control over CAT off the radio, how was it supposed to work?
"CI-V Transceive" must be ON.
You have RTS and DTR High one should be low ...

The driver was installed correctly and did not show problems with 3 other programs so I assumed the problem was elsewhere.
Your suggestion Terry helped me with this topic - Thank You.

Problem has been solved.
I removed the driver from the computer, restarted my computer and reinstalled the same driver - it helped.
I did not do this before because the rest of the programs worked properly - that made me wrong.
