Hm, I think you have to connect one device to SCSI bus, because you get
"answer" of the devices connected to the bus.
I am not so familiar with SCSI programming and had a superficial look (what
the hell means "flüchtiger Blick" in english?) at the howto.
But there is speech of sending and receiving of SCSI commands and therefore
you should have a device connected, I think.
The mail problem happens to me, too - but only for four days... ???
Greetings, Dietmar
