Failover
Failover is a connection feature that is enabled using the Security properties
sheet. It forces the terminal to “ping” the intended device before making a
connection to it. The function operates when
Failover Enable is enabled on the
Security properties sheet. Failover is global and wholly automatic to the terminal. It
will work regardless of what connection you are trying to make, or what type of
account you are logged in using. See “Security Properties” for more information
about this function and how to invoke the properties sheet.
Note
Ping (Packet Internet Groper) is a network utility. It
tests communication with nodes in a network by
sending a packet to each selected node. Ping then
waits to receive the echo response from that selected
node.
Failover operates as follows:
1. The terminal pings the intended connection, to determine whether or not it is
available.
2.
If pinging the intended device fails, the terminal pings each successive
connection in the list.
3. For each connection:
a.
If ping is successful, the connection is made.
b. If ping is not successful, the terminal pings the next connection.
c.
If the next connection is a serial connection, ping will stop. Ping will not work
on a serial connection. Failover will not continue after encountering a serial
connection, but will launch the serial connection if it is valid.
