Gentlemen,
I am just going to improve my EZGPIB utility so that it can make use of more
than one GPIB-interface (supported by GPIB32.Dll, not Prologix). I have been
trying to enumerate all detected interfaces by using
ibdev(bi,0,0,T300ms,0,1)
in a loop where bi starts with "0" and is incremented by "1" until the
result of the call gets negative. Much to my surprise this loop detects 4
(!) interfaces GPIB0 to GPIB3 even if absolutely NO interface is connected
to the pc.
What am I doing wrong. Is "4" the maximum number of interfaces that may be
handled by GPIB32.Dll ????
What do I need to do to find the real number of detected interfaces ?????
Best regards and TIA for your answers
