Host-to-Switcher Communications

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
switcher executes the command and sends a response to the host device. All responses
from the switcher to the host end with a carriage return and a line feed (CR/LF =
signals the end of the response character string. A string is one or more characters.
