	4: Using Setup Mode for Configuration
Response
Character Response	A single character is transmitted to the serial port when there is
	a change in connection state:
	C = connected, D = disconnected, N = host unreachable.
	This option is overridden when the Active Start Modem Mode
	or Active Start Host List is in effect. Default setting is Nothing
	(quiet).
No Active Startup	Does not attempt to initiate a connection under any
	circumstance. Default setting.
With Any Character	Attempts to connect when any character is received from the
	serial port.
With DTR Active	Attempts to connect when the DTR input changes from not
	asserted to asserted.
With a Specific Start	Attempts to connect when it receives a specific start character
Character	from the serial port. The default start character is carriage
	return.
Manual Connection	Attempts to connect when directed by a command string
	received from the serial port. The first character of the command
	string must be a C (ASCII 0x43), and the last character must be
	either a carriage return (ASCII 0x0D) or a line feed (0x0A). No
	blanks or space characters may be in the command string.
	Between the first and last command string characters must be a
	full or partial destination IP address and may be a destination
	port number.
	The IP address must be in standard dot-decimal notation and
	may be a partial address, representing the least significant 1, 2,
	or 3 bytes of the remote IP address. The period is required
	between each pair of IP address numbers.
	If present, the port number must follow the IP address, must be
	presented as a decimal number in the range 1-65535, and must
	be preceded by a forward slash (ASCII 0x2F). The slash
	separates the IP address and the port number. If you omit the
	port number from a command string, the internally stored remote
	port number starts a connection.
	If a partial IP address is presented in a command string, it is
	interpreted to be the least significant bytes of the IP address and
	uses the internally stored remote IP address to provide the most
	significant bytes of the IP address. If the IP address entered is
	0.0.0.0/0, the device server enters Monitor Mode.
	For example, if the remote IP address already configured in the
	unit is 129.1.2.3, then an example command string would be
	C3/7. (This would connect to 129.1.2.3 and port 7.) You may
	also use a different ending for the connection string. For
	example, C50.1/23 would connect you to 129.1.50.1 and port 23.
Table 4-10. Manual Connection Address Example
Command String	Result if remote IP is 129.1.2.3 and remote port is 1234
C121.2.4.5/1	Complete override; connection is started with host 121.2.4.5, port 1
C5	Connects to 129.1.2.5, port 1234
C28.10/12	Connects to 129.1.28.10, port 12
