3.10 MODE SELECT (10) command
The MODE SELECT(10) command (see table 72) provides a means for the application client to specify medium, logical unit, or
peripheral device parameters to the device server. See the MODE SELECT(6) command (see 3.9) for a description of the fields and
operation of this command. Application clients should issue MODE SENSE(10) prior to each MODE SELECT(10) to determine
supported mode pages, page lengths, and other parameters. Device servers that implement the MODE SELECT(10) command
shall also implement the MODE SENSE(10) command.
