Request :Theta Casablanca IV Receiver Support in Simple Control

Hi wondering if we could get full two way support for Theta Casablanca. It has simple serial support where it provides feedback for all key status on any state change. This device has been around for 20 years and upgraded to latest the for all it’s owners so there are alot of them around.

Link to RS232 doc (

Alternatively if there is a custom feedback option we could add these devices ourselves so cn we request that too?

Thanks Rick
