INCOMING CONNECTION:
Never Accept Incoming:
Rejects all external connection attempts.
Accept with DTR Active: Accept external connection requests only when the DTR input is asserted.
Cannot be used with Modem Mode.
Always Accept: Accept any incoming connection when a connection is not already
established. This is the default setting.
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).
ACTIVE STARTUP:
No Active Startup:
No attempt to initiate a connection under any circumstance. This is the
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 Char: Attempts to connect when it receives a specific start 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 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 presented 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 the port number is omitted from a command string, the internally stored
remote port number is used to start a connection.
For Active Start options requiring internally stored destination IP address
and port number, the unit will not attempt a connection if this information is
not configured (all zeros).
If a partial IP address is presented in a command string, it will be
interpreted to be the least significant bytes of the IP address and will use the
internally stored remote IP address to provide the most significant bytes of
the IP address.
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.
