The command graphic

indicates commands that are used for the IEEE-
488 interface. This is all the commands, except for those used for RS-232 operations.
(See “Commands for RS-232 Only.”) All commands are transferred over the IEEE-488
as data, except for the commands LOCAL, REMOTE, and LOCKOUT, which are
implemented per IEEE Standards as messages (see Table 5-7).
