The Command and Response tables list valid ASCII (for Telnet or RS-232) command
codes, the corresponding URL (Uniform Resource Locator) encoded (for Web browsers)
command codes, the DMP64 responses to the host, and a description of the command
function or the results of executing the command.

NOTE:
For Web encoding only: data is directed to the specified port and must be
encoded (URL encoding) if it is non-alphanumeric. Change any non-alphanumeric
character (%, +,
|
,
}
, and so on) within the data section into the corresponding
hexadecimal equivalent, %xx, where xx represents the two-character hex byte. For
example, a space (hex: 20) would be encoded as %20 and a plus sign (hex: 2B)
would be encoded as %2B.
