If somebody wants to write up some code that takes two bytes and turns them into a row and column address, reversing the transformation described on that page - *without* looking at the TN3270 dissector - and send them to me or the list for inclusion in that routine, that might help. (I've already seen the offending code, so I'm not sure I should write any replacement.)
Well, I found an online version of the IBM 3270 data stream programmer's reference, and redid that whole section of code a bit differently - having forgotten what the heck that macro was doing (a rare time I can be grateful for short-term memory not making it into long-term memory :-)) - and am compiling it now. The new version also indicates the address format in the protocol tree item (14-bit binary or 12-bit coded), and also specially handles the format that manual claims is reserved. (Oh, and it notes that we don't handle 16-bit addressing.)
I'll check that in, and revert the license.
