command has completed execution before executing the
next command. For example:
OUT 1 V; *WAI
You can also use the status commands *OPC and *OPC?
to detect the completion of overlapped commands.
g)
Sequential Commands
Commands that execute immediately are called sequential
commands.
The detailed command descriptions in section 10 show a
check mark T beside Sequential for sequential commands.
The majority of commands are sequential.
h)
Commands for RS-232 Only
Several commands are used only for RS?232 serial
operation because these functions must be implemented
as IEEE uniline (single control line) bus management
messages per the IEEE Standards. For example, the
command REMOTE could be sent as data over the IEEE-
488 interface to place the CL3001 into remote operating
mode, but it is not because the IEEE Standards call for the
remote function to be sent to the device as the uniline
message REN. This is also true for several other
commands and functions, as shown in table 6 below with
their RS-232 equivalents.
For these commands, the detailed command descriptions
in section 10 show a check mark
beside RS-232, but
no check mark
beside IEEE-488.

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.
