oo82162A simulates an HP-82162A including "PRT" and "ADV" buttons, also a mode selector.

Those buttons and the selector switch require a controller emitting auto-IDY frames. The HP-IL module sends them out at a 10 ms pace, same does V41, typically. As kind of a "loop sound check" oo82162A measures the time interval of 20 consecutive IDY frames. In case there are none at all or the interval is outside 25% of the expected 200 ms, I assume there is something wrong, either with the controller or the loop, and the buttons remain inactive.
When you place within the loop an HP-41 equipped with a Dev-IL ROM a considerable delay of IDY frames is expectable. Then the interval must be adjusted in oo82162A.ini as described there. Now with V41 version 9N I observe for the first time also a significant delay if there is no Time chip in the setup (327 ms for 20 IDY frames instead of 208 ms with Time). Christoph is informed.
BTW, there are few others simulating the HP-82162A, while oo82162A is the only one (AFAIK) that prints barcode like the role model.

Alas, I do not know if the bar height is the same, I never saw BC output from real machinery. If it differs recognisable please let me know.
