Appendix C: Remote Command Set
This section describes the remote command set for the waveform monitor and
provides examples of typical usage. The remote command set is a versatile and
convenient interface that conforms to industry standards for programmable
instruments.
The waveform monitor permits remote operation through the RS-232 port on the
rear panel. Remote communication parameters are described in Appendix B:
Remote Operation.
The waveform monitor was not designed to be machine-driven; consequently,
characters can be dropped if they are input while the processor is carrying out
other operations. To compensate, the code for a remote communications retry
program has been included at the end of this section. This program ensures that
characters are not dropped when they are input into the waveform monitor. You
may type commands from your work station with or without the program;
however, if you want to create machine-driven test and measurement protocols,
use the retry program provided.
The symbols used in the descriptions of the remote commands are shown in
Table C–1.

Symbol Meaning
 Group; one element is required
[ ] Group; elements are optional
OR; separates a list of arguments
The commands in this section are arranged alphabetically by groups of similar
commands. Commands with similar syntax are explained in tables with
argument options and comments about each command. Examples of possible
command strings and responses are then listed below the tables. The rest of the
commands are described individually with examples of syntax and typical usage
given for each command.
In the following descriptions, the capitalized letters in the Syntax descriptions are
the minimum letters necessary for the waveform monitor to recognize the
command. Commands and arguments are not case sensitive.
Most commands have a query form. Generally, you can query at any point along
a command string back to the root but you can not query arguments. In the
following command descriptions, queries are given below the command syntax
