7: Setup Mode: Channel Configuration
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).
Does not attempt to initiate a connection under any
circumstance. Default setting.
Attempts to connect when any character is received from the
serial port.
Attempts to connect when the Modem Control In input changes
from not asserted to asserted.
Attempts to connect when it receives a specific start character
from the serial port. The default start character is carriage return.
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 decimal-dot 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.
If an IP address does not follow the first command string
character (which is "C"), the subsequent character string is
46
