shows a Guardian TN3270 Server configuration that has a single TCP/IP
configuration. Note that port number 2000 has been assigned to the Guardian TN3270
Server to avoid a conflict with the Tandem TELSERV (Telnet server) program default
port number 23.
You can have more than one LAN controller in large configurations. In this
environment, you can have one or more TCP/IP processes. Different copies of the
Guardian TN3270 Server can access different TCP/IP processes.
