g. Supported functions
The bit positions shown below are valid only when the CHANGE DEFINITION command is set
so that the SCSI-2 or SCSI-3 mode INQUIRY data are transferred, and the functions which the
IDD supports are shown in the bit correspondence.
"1" indicates that that function is supported and "0" indicates that that function is not supported.
When the CHANGE DEFINITION command is not set so that SCSI-2 mode INQUIRY data are
transferred, "0" is displayed in all these bit positions.
