2. Verify the settings, as defined in Table 4.
Table 4 TCP/IP Settings
Parameter Setting
IP Address To assign a static IP address, enter it in this field
The IP address must follow the format XXX.XXX.XXX.XXX, where
each XXX is a number between 0 and 255. The default IP address
mask is 192.0.0.192.
Subnet Mask To assign a static subnet mask, enter it in this field
The subnet mask must follow the format XXX.XXX.XXX.XXX, where
each XXX is a number between 0 and 255. The default subnet
mask is 0.0.0.0. The server interprets a subnet mask of 0.0.0.0 or
255.255.255.255 as no subnet mask specified.
Default Gateway Sets the default gateway, if your network is attached to other
networks
Boot Method Set to STATIC for a static IP address, set to DHCP or AUTO to
attempt to automatically assign the IP parameters from a network
server.
TCP Timeout Sets the timeout and reset values for the TCP connections

Using AT Modem Commands
NOTE: The AT Command filter cannot be used in a FIPS 140-2 approved mode. The Cryptographic
Officer must leave the port filter setting as TRAP (the factory default value).
The Serial Device Server firmware has an optional data filter for configuring using AT style modem
commands with the serial port. This feature allows devices with an existing AT command interface to
configure the unit, if the AT commands can be properly modified. You must be familiar with the general
operation of AT commands. Note that AT command processing is not enabled by default. Use the
command SET PORT S1 FILTER AT to enable this feature.
All commands begin with AT and are terminated by a new line unless noted below. While standard AT
commands are defined to be 40 characters or less (not including the AT), the server accepts commands
of up to 80 characters.
