Problem sending only one byte with ibwrt()

[dakota56]

If I send only one byte of data with ibwrt() command, it doesn't work with whatever settings (EOS,EOI,..) I chose. I got the error (ENOL : no listener).
Did somebody get the same problem ?

ENOL indicates that there is no listener on the bus. This is probably not related to the settings on the controller. Are you correctly addressing a device to be a listener? If so, is there some indication on the device that it is addressed to listen?

Also, your post seems to indicate that sending more than one byte works. Is this true?
