With a Specific Start
Character
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
may be in the command string. Between the first and last command
string characters must be a full or partial destination IP address and
can include 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 octet 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 C23/7. (This
would connect to 129.1.23 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.
