I would be very surprised if the core structure of DUML had changed, or was incorrectly reverse engineered.

Please make sure you're not misinterpreting something.
This change would have very large implications.

fact is i cannot formulate a packet to receiver "1f". "-r 1501" translates to "2f" without my patch. I had same oddities with the sender parameter: 1001 translates to "2a". which is ok, because I need "2a", but what if i needed "1a"? Maybe I'm grossly misinterpreting sth here and the "1f" is accomplished by some other parameters I havent considered. If so, I stand corrected. Please, how would you correctly send a duml to "1f"?

m1501 means --receiver_type 15 and --receiver_index 1. In this patch, you just removed one bit from "receiver_type". Definitely not what you wanted.

Ok, I see my error now. the data field is 5 bits, not 4. I'm sorry.
