For these commands, the detailed command descriptions in section 10 show a
check mark beside RS-232, but no check mark beside IEEE-488.
Table 6 - Commands for RS-232 Only
IEEE-488 Message RS-232 Equivalent
GTL LOCAL command
GTR REMOTE command
LLO LOCKOUT command
i) Commands for IEEE-488
These are all of the commands except for those used for RS-232 only, as
described above. All commands are transferred over the IEEE-488 as data,
except for the commands LOCAL, REMOTE, and LOCKOUT, which are
implemented per the IEEE Standards as uniline messages.
The detailed command descriptions in section 10 show a check mark T beside
IEEE-488 for these commands.
9.6.2 Command Syntax
The following syntax rules apply to all of the remote commands. Information about the
syntax of response messages is also given.
