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 SMD 101 responses to the host, and a description of the command function or the results of executing the command.

E  =

CR/LF (carriage return/line feed) (hex 0D 0A)

Carriage return (no line feed, hex 0D)

(for URL-encoded commands, use the pipe character,  , instead)

Space character (%20 for web browser) Pipe (vertical bar) character

Asterisk character (which is a command character, not a variable)

Escape key (hex 1B)

(use W instead of Esc for Web browsers)

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 (%, +, }) within the data section into the corresponding hexadecimal equivalent, %xx, where xx represents the two‑character hex byte. For example, a space (hex: 20) is encoded as %20, and a plus sign (hex: 2B) is encoded as %2B.
