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.

Ok Terry I send correct support file. Today I have change baudrate for 115200 CAT not working (Red Lamp) 38400 the same problem . 19200 work - very unstable -not for work. I checked WSJT-X program for 115200 work fine. Maybe the 7300.ini file I got some bad or old because therewas no file in the ins...

Ok
You have set:
CI-V USB Port - UNLINK from Remote
CI-V USB Baud Rate - 115200
CI-V Baud Rate - 19200 it probably doesnt matter ...

I think the problem is in Rigs file Icom 7300.ini
Loger 32 have the same setings com, baudrate , stop bits ,polling int.=1000ms etc.)and work fine.

I'm using Omnirig, changing to administrator rights has not improved. The bitrate is 19,200 because only the trx connection is set up just as the rest of the settings(bitstop etc) are correct as in other programs Loger32, JTDX, WSJTX- work properly. You need to set your radio to 115.200 baud rate. ...

Ok please email address ...

I changed to 100ms - nothing improved .
Click on the spot and nothing happens sometimes after 30s interrupt, as it is on the same band it's faster
