Using the Command and Response Tables

SIS commands consist of a string (one or more characters per command field). No special
characters are required to begin or end a command sequence. When the AXP 64 C AT
determines a command is valid, it executes the command and sends a response to the host
device. All responses end with a carriage return and a line feed (CR/LF =
end of the response character string.
For programming, certain characters are more conveniently represented by their
hexadecimal than their ASCII values. The following ASCII-to-hex conversion table shows
the hexadecimal equivalent of each ASCII character:
