Setting BOM bit seems to help, now it does not abort immediately anymore but attempts to execute MODE_SELECT command (which is not yet implemented).
I guess these bits are obsolete because "SCSI Stream Commands" document from 2003 does not mention them. (Wangtek manual looks nice, thanks)
Amix only reads 14 bytes of sense data, I guess it means Amix only works with SCSI-1 tape drive.
