13 Writes a modified mode page to \fIDEVICE\fR. Uses the SCSI MODE SENSE (6
14 or 10 byte variant) command to fetch the existing mode data which includes
15 a mode page (or subpage). It then combines that with the contents,
16 potentially masked, and writes the modified mode page with the SCSI MODE

169 The recommended way to modify a mode page is to read it with a

177 Two fields differ between what is read from the device with MODE SENSE and
178 what is written to the device with MODE SELECT:
179 the mode data length is reserved (i.e. zero(es)) in a MODE
181 mode (sub)page is reserved (zero) in a MODE SELECT command.
186 the default mode page values (i.e. the mode page values chosen by the
187 manufacturer of the device) as both the current and saved mode page
