Host-to-Unit Instructions
SIS commands consist of one or more characters per field. No special characters are required
to begin or end a command character sequence. When a command is valid, the unit
executes the command and sends a response to the host device. All responses from the unit
to the host end with a carriage return and a line feed (CR/LF = ]), which signals the end of
the response character string. A string is one or more characters.
