I have not heard much of this product so far. What did you have in mind for it when used with Comfort?
Currently Comfort UCM is able to send any arbitrary command to an external device through RS232 or Ethernet, but firmware needs to be developed to receive commands the other way. Hence we can do this for products which are widely used.
The problem is that interfacing to products like Companion will require the other manufacturer to add support for Comfort in the screen.
We are quite open as far as our communications protocol, but others may not be so. Hence your question is better directed at Cortexa if you have coontact with them
