See Section 22.3 for information about the errors and

See Section 22.3 for information about the errors and
exceptions that can occur for this setting.
011b Space to end of data
If you set the Code field to 011b, the CTS ignores the
setting of the Count field. Instead, it spaces forward
until it encounters EOD (blank tape for 8200 format).
The tape is positioned so that a subsequent WRITE
command can append data after the last block,
filemark, or setmark (8500c format only) written before
the end of data.
100b
(EXB-8505
only)
Space over
n
setmarks
When you set the Code field to 100b, the EXB-8505
ignores the setting of the RSmk bit on the MODE
SELECT Device Configuration page (Page Code=10h).
In addition, filemarks are ignored if you are spacing
over setmarks.
If you use this Code field setting and the tape is not in
8500c format, the EXB-8505 returns Check Condition
status with the sense key set to Illegal Request (5h).
The Fault Symptom Code is CEh.
For the EXB-8205, this value is reserved. If you set the
Code field to this values, the EXB-8205 returns Check
Condition status with the sense key set to Illegal
Request (5h).
010b
Reserved
If you set the Code field to one of these values, the
CTS returns Check Condition status with the sense key
set to Illegal Request (5h).
