The commands listed in the following tables perform the same functions, but are encoded
differently to accommodate the requirements of each port (Telnet or browser).
DMP 64-initiated Messages

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 DMP 64
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 = ] ),
signaling the end of the response character string.
When programming, certain characters are more conveniently represented by their
hexadecimal rather than ASCII values. The table below shows the hexadecimal equivalent
of each ASCII character:

If the DMP 64 is off and an RS-232 connection is set up (the PC is cabled to the
DMP 64 and a serial communication program such as HyperTerminal is open), the
connected unit sends these messages by RS-232 when first powered on.
If the DMP 64 is on, it sends the boot and copyright messages when a Telnet
connection to the DMP 64 is first opened. The day of the week, date, and time are
shown when the DMP 64 is connected by Telnet, but not by RS-232. If using a Telnet
connection, the copyright message, date, and time are followed by a password
prompt.
