SYNTAX NOTES

Square brackets [ ] are used to enclose the list of valid channels for a command, or a list of command options separated by
the vertical separator bar | character. This character is for syntax only, and is not to be entered as part of the command. By
default, if no channel number is specified, Channel 1 is selected.

A literal argument denoted by <character data> indicates a word or series of characters, which must exactly match one of
the choices for the command. An argument denoted by <numeric_value> requires a string which, when converted to a
number, is within the range of valid arguments. Numerical values can generally be in any common form including decimal
and scientific notation. <Boolean> indicates an argument which must be either true or false. Boolean arguments are
represented by the values 0 or OFF for false, and 1 or ON for true. Queries of Boolean parameters always return 0 or 1.

Curly braces { } are used to enclose two or more possible choices for a mandatory entry, separated by the comma character.
One of the enclosed options MUST be inserted into the command, and the braces are not to be entered as part of the
command.
