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.

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 (,).
