- Subject : 9.2.13 SPACE Command, Rev 6a, page 9-30
-
-
- Issue :
- -------
- The intent, agreed by the DDS Manufacturers Group, was for the Code field,
- Byte 1, DB0,1,2 to take the following values
-
- 1 0 0 Reserved
- 1 0 1 Setmarks Optional
- 1 1 0 Sequential Setmarks Optional
-
- This set permits DB1,0 to take the values "01" for both types of mark and
- "11" for both types of sequential mark, with DB2 specifying whether
- Filemark(s) or Setmark(s). This makes implementation consistent and simple.

- Proposed text :
- ---------------

- DB(2) DB(1) DB(0) Description Support
- ----- ----- ----- ----------- -------
