When SIS commands are used through a Web browser, the URL reference is used
below to shorten the examples. This would in practice be the full URL of the
control interface and Web page reference including all path information.
(e.g., http://192.168.254.254/index.html)
To send any of the commands using a Web browser you need to prefix them with
the full URL followed by ?cmd=. See URL Encoding later in this chapter.
N
With Telnet you can use either the Escape commands or the W commands, and
the carriage return or the pipe ( ) character. With the Web browser you are
required to use the W commands and the pipe character.
In either method {Data} = Data is directed to a specified port and must be encoded
if non-alphanumeric.
The Command/response table for Simple Instruction Set (SIS) commands later in this
chapter lists the commands that the DVS 304 scaler recognizes as valid, the
responses that are returned to the host, a description of the command’s function or
the results of executing the command, and an example of each command in ASCII
(Telnet) and URL Encoded (Web).

Upper and lower case text can be used interchangeably except where noted.
