SERIAL SERVER NAME
Serial Server Name
is a unique name assigned to the serial server. It must be a valid
hostname as defined by RFC-952 and RFC-1123. The rules are:
It must consist only of the characters "A" to "Z", "a" to "z", "0" to "9" or "-"
It can start or end with a letter or a number, but it must not start or end with a "-".
It must not consist of all numeric values.
SERVER SERIAL PORT NUMBER
The
Server Serial Port Number of the currently selected port is shown in this field.
VESR901-x serial servers feature one serial port.
VESR902D-x and VESR902T-x serial servers feature two serial ports.
SERIAL WATCHDOG
Serial Watchdog
controls the duration of serial inactivity when the serial port is
determined idle and causes all connections for that serial port to be forced closed.
The range is 1 through 65535 milliseconds.
SUBNET MASK
The
Subnet Mask
specifies the network mask the serial server uses when on a
subnetted network.
For a Class A network (IP addresses 0.0.0.0 through 127.255.255.255) the default
subnet mask is 255.0.0.0.
For a Class B network (IP addresses 128.0.0.0 through 191.255.255.255) the default
subnet mask is 255.255.0.0
For a Class C network (IP addresses 192.0.0.0 through 233.255.255.255) the default
subnet mask is 255.255.255.0
