Description of the feature you're suggesting.

I'm hoping that somebody can add support for DTM System (Keeloq based) protocol - I know DTM Neo is already implemented but this seems to be a different protocol - maybe very similar so easy to add? The transmission frequency is 433,868 MHz with AM modulation I was able to pair the partially decoded KeeLoq (by using the "Send" function in the decoded view) with the gate but it worked just once as the counter did not increment.
