Error Responses

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.

Symbol definitions

] =

•=

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.

When the SMD 101 is unable to execute the command, it returns an error response to the host. The error response codes and their descriptions are as follows:

E10

E12

E13

E14

E17

E22

Unrecognized command	E24	Privilege violation
Invalid port number	E25	Device is not present
Invalid parameter (number is out of	E26	Maximum connections
range)		exceeded
Not valid for this configuration	E28	Bad filename or file not found
System timed out	E30	Hardware failure
Busy	E31	Attempt to break port pass-
		through when not set
