A talk-only, listen-only system without controller is somewhat off-topic for a site about "everything HP41". But since V41 is virtual-IL-enabled it is close enough to be posted here.
An example for a talk-only, listen-only system might be a voltmeter logging readings on a printer. An HP82162A could be used in such a setup. So I added the L2 interface function to my simulation. As measuring device I butchered the same simulation, reused the HPIL drudgery, added the T5 function (act on local message ton) and a routine reading the wall clock. This "clock read out" is a nice example from 1979 of Mike Cowlishaw, the developer of REXX.
I proudly present the (to my knowledge) first working virtual HP-IL setup without controller.
The result:
Find the talk-only device for this test in attached ZIP, the oo82162A simulation with listen-only option will be published soon.
