A couple of quick things to try...Try using 1 stop bit. Failing that, try a slower baud rate.

I'm trying to setup CAT to control my rig; my settings are:

COM4
8 data bits
2 stop bits
no handshake
other pins on default

The Test CAT button works, it sets to green, and PTT also correctly starts transmitting.

The issues:

When selecting a band from the dropdown, the rig is correctly set to the appropriate frequency. A couple of seconds later, when the system polls the current frequency, it's 100 times higher and it ends in 48. E.g.: 40m sets to 7,074.000 Two seconds later, it becomes 707,400.048.

A few seconds later, I get a timeout error and the rig disconnects.

Any help is appreciated.
