Host to Receiver Communications

SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the VLR 102 determines that a
command is valid, it executes the command and sends a response to the host device.
All responses from the receiver 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.
