Cannot be used with Modem Mode.Always Accept Accepts any incoming connection when a connection is notalready established. Default setting.b) ResponseCharacter Response A single character is transmitted to the serial port when there is achange in connection state:C = connected, D = disconnected, N = host unreachable.Single character mode specifies the character response. The IPaddress of the host connecting to the unit displays when the unitis in verbose mode. This option is overridden when the ActiveStart Modem Mode or Active Start Host List is in effect.Default setting is Nothing (quiet).c) Active StartupNo Active Startup Does not attempt to initiate a connection under anycircumstance. Default setting.With Any Character Attempts to connect when any character is received from theserial port.With DTR Active Attempts to connect when the DTR input changes from notasserted to asserted.With a Specific StartCharacterAttempts to connect when it receives a specific start characterfrom the serial port. The default start character is carriage return.Manual Connection Attempts to connect when directed by a command stringreceived from the serial port. The first character of the commandstring must be a C (ASCII 0x43), and the last character must beeither a carriage return (ASCII 0x0D) or a line feed (0x0A). Noblanks or space characters may be in the command string.Between the first and last command string characters must be afull or partial destination IP address and may be a destinationport number.The IP address must be in standard decimal-dot notation andmay be a partial address, representing the least significant 1, 2,or 3 bytes of the remote IP address. The period is requiredbetween each pair of IP address numbers.If present, the port number must follow the IP address, must bepresented as a decimal number in the range 1-65535, and mustbe preceded by a forward slash (ASCII 0x2F). The slashseparates the IP address and the port number. If you omit theport number from a command string, the internally stored remoteport number starts a connection.
