Half open/closed might be possible too if people were interested. All open could happen too, but it would be a separate effort from what I'm doing now. -- Chuck Tuffli Agilent Technologies, Storage and Networking To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
