|Strange HP-IL behavior.|
Message #1 Posted by Marwan Joury on 26 July 1999, 2:58 p.m.
I am experiencing some strange behavior from an HP-IL module (HP41). When connected to a single device everything works fine. When two devices are connected the second device returns errors. This has been reproduceable both with the following configurations:
1 - disk drive - printer 2 - printer - disk drive 3 - disk drive - disk drive
The second device always returns an error -- change the HP-IL module and everything works fine.
Does anyone have any ideas as to what may be causing this (yes I know the module has somehow gone bad ), has anyone else ever experienced something like this?
