The Default Gateway address sets the default route to remote networks, enabling
users to access the serial server from outside the local network.
DELIMITER 1, DELIMITER 2 AND DELIMITER REMOVAL
Delimiters and Delimiter Removal enable you to control how characters received on
a serial port are sent across the network. Delimiters are ASCII characters specified by
the user when configuring the serial server. The serial server takes action when it
recognises the specified character(s) on its serial port.
DELIMITER 1
Delimiter 1 is a start delimiter. The range of ASCII values is 0 through 255.
DELIMITER 2
Delimiter 2 is an end delimiter. The range of ASCII values is 0 through 255.
DELIMITER REMOVAL
Delimiter Removal controls removing of Delimiter 1 and Delimiter 2 from the
received characters before the received characters are sent to the network.
HOW DELIMITERS WORK
When only Delimiter 2 (the end delimiter) is enabled, characters received by the
serial port are accumulated in a buffer. When the end delimiter is received on the
serial port, the buffered characters, including the end delimiter, are sent to the
network. All characters received after the end delimiter are again buffered until
another end delimter is received.
When both Delimiter 1 (start delimiter) and Delimiter 2 (end delimiter) are enabled,
characters received by the serial port will be discarded until the start delimiter
character is detected on the serial port. The serial server then buffers the start
delimiter character and all subsequent characters received after it until the end
delimiter is detected. When the end delimiter is received, the buffered characters,
including the start and end delimiters, are sent to the network.
When Delimiter Removal is enabled it removes the delimiter character(s) before
sending the other characters across the network.
DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol used on special servers
that supply IP addresses to network nodes on request.
