Grammar of messages

This section describes the grammar to send program messages via GPIB.
Program messages are messages that the user sends to the instrument from
the external controller to control the instrument. A program message consists
of one or more commands and their necessary parameters.
Upper/lower case sensitivity
Upper/lower case insensitive.
Program message terminator
A program message must be terminated with one of the three program
message terminators: <new line>, <^END>, or <new line><^END>. <^END>
indicates that EOI on the GPIB interface becomes active at the instant when
the immediately previous data byte is sent. For example, the OUTPUT
command of HTBasic automatically sends the message terminator after the
last data byte.
Parameters
A space (ASCII code: 32) is required between a command and its first
parameter. When sending several parameters in a single command, separate
each parameter with a comma (,).
Message including several commands
When sending two or more commands in a single message, separate each
command with a semicolon (;). The following example shows how to send the
*CLS command and the :STAT:PRES command in a single message using
HTBasic.
OUTPUT 717;"*CLS;:STAT:PRES"

Remote mode

the screen.
Press [Local/Lock] to cancel the remote mode.
