The Advanced tab is used to manage network traffic to the host. The following configuration settings are available:
Enable “Hot
Back Up” IP Host Names
When this option is selected, you can specify alternate IP host addresses
and TCP ports to connect to if the primary connection attempt fails for
some reason. Use the Add,
Edit and Remove
buttons to add, modify or remove an address and/or port number from the
list. Use the Up and Down buttons to move a selected
address up or down in the list.
Enable Keep Alive
When this option is enabled, PASSPORT sends a periodic timing signal to
the gateway or mainframe to ensure that the connection is not idle long
enough to be terminated. This feature can also be used to keep an internet
connection alive.
Timer value (min)
This value specifies the regular interval at which PASSPORT sends a timing
signal. The value may be between 1 minute and 1440 minutes (1 day). The
default is 15 minutes.
Keep Alive Sequence
The Keep Alive Sequence area allows you to choose between two timing signal
options: NOP and Timing Mark. The default
is NOP.
Note: When using a dial-in connection with an internet service provider (ISP), you may be disconnected after a period of idle time, even though the Enable Keep Alive option is selected. To minimize the chances of this occurring, you can change the gateway port number to something other than 23, the default telnet port.
