buffer.

Terminators

A program message terminator identifies the end of a command string. These are
the valid terminator sequences:
• <NL>
• <^END>
• <NL><^END>
Many computers terminate with <CR><NL><^END> (Carriage Return - New Line
- EOI). A carriage return (<CR>) is read as white space.
The LDX-36000 terminates its responses with <CR><NL><^END>, unless the
TERM command is used to change it.
If problems are encountered with GPIB communications, the terminator string can
sometimes be the cause. Refer to the computer's GPIB controller manual for
information on configuring its terminator string.

Command Separators

More than one command may be placed in the same command string if each
command is separated by a semicolon. The semicolon can be preceded by one
or more spaces. For example:
LAS:LIM:I 15.5; las:lim:v 4.5; LAS:CAL:P?
LAS:MODE:CW

Parameters

Some commands require a parameter. The parameter must be separated by at
least one white space.
The syntax symbol <nrf value> refers to the flexible numeric representation
defined by the GPIB standard. It means that numbers may be represented in
