Chapter 1 Getting Started 893-386-B 1- 1 The Model 3395/3395A Terminal Server is a combination of hardware and software that links users at serial devices, such as terminals, to resources on both local area networks (LANs) and wide area networks (WANs).
Getting Started 1- 2 893-386-B The user in Figure 1-1 has made a connection to the UNIX host on the LAN through the terminal server. He can now read databases, send mail, and run applications on this host. He can also connect to the VAX host, the IBM host, or a serial device on the other terminal server.
Getting Started 893-386-B 1- 3 The remaining sections of this chapter explain how you can use the terminal server in a network such as this one. These sections include the following topics: • Using .
Getting Started 1- 4 893-386-B Logging On to a Terminal Server Port If your terminal is connected directly to a terminal server port, press the <Return> key until one of the following prompts appears on the screen.
Getting Started 893-386-B 1- 5 Managing Sessions The connection between a terminal server port and a device on the network is called a session . You can establish a session with a LAT service, a Telnet host, an IBM host, or another terminal server after you log in to the terminal server port.
Getting Started 1- 6 893-386-B Suspending a Session When you suspend a session, you recall the Model 3395/3395A command interface without terminating the connection to the remote resource. Later, you can reopen the session and continue with your work.
Getting Started 893-386-B 1- 7 To switch from session 2 at a LAT service to session 1 at FINANCE.SUN.COM, you could use a sequence like this with the RESUME command, beginning at the LAT service: $ $ <BREAK> FINANCE.SUN.COM session 1 resumed Disconnecting From a Session You can disconnect from a session in two ways.
Getting Started 1- 8 893-386-B Using UNIX Aliases for Terminal Server Commands The Model 3395 Terminal Server software provides several UNIX equivalents, or aliases, for Model 3395/3395A Terminal Server commands.
Getting Started 893-386-B 1- 9 Summary The Model 3395/3395A Terminal Server provides you with access to many resources on the network that might be unavailable to you otherwise. To use the terminal server, you log on to a terminal server port and establish sessions with hosts or other terminal server ports.
Chapter 2 The User Interface 893-386-B 2- 1 This chapter describes how to use the terminal server command interface and the terminal server menu interface.
The User Interface 2- 2 893-386-B Users at Nonprivileged and Privileged ports can change the defaults for the editing characters with the SET PORT command, so the characters on your port may not have the same functions as the ones shown in Table 2-1.
The User Interface 893-386-B 2- 3 The following example shows how to use the command line recall and editing features. Suppose that you enter the following command, which contains a typographical error: TS3395> shw port characteristics The terminal server would not accept the command because you spelled SHOW incorrectly.
The User Interface 2- 4 893-386-B The user at this port can now use <CTRL><L> to suspend an active session. Because this is a SET command, it takes effect immediately, but remains in effect only until you log off of the port.
The User Interface 893-386-B 2- 5 Telnet Session Management Characters Telnet session management characters provide command line editing and process management during a Telnet session. Table 2-3 lists the keywords you use with the SET PORT commands to assign Telnet session management functions to control characters Table 2-3.
The User Interface 2- 6 893-386-B Using the Terminal Server Menu The Model 3395/3395A Terminal Server software running on your terminal server may have a menu interface rather than a command interface. You will know this if a menu appears on your screen rather than the TS3395> prompt when you log on to the terminal server port.
Chapter 3 Using Model 3395/3395A Terminal Server Commands 893-386-B 3- 1 This chapter describes the commands you can use at Secure ports. These commands establish sessions, display information about LAN destinations, sessions, and services, and allow you to specify some characteristics of your own port.
Terminal Server Commands 3- 2 893-386-B Viewing and Changing Information in the Terminal Server Databases The terminal server maintains two files of data, or databases, that contain information about the terminal server and the devices you can reach on the network.

Chapter 6 Transferring Files With a Personal Computer 893-386-B 6- 1 A personal computer, or PC, that runs terminal emulation software and has a serial port can run on the terminal server in the same way as a terminal. This chapter explains how to transfer files between a PC and a host or another PC on the LAN through the terminal server.
Transferring Files 6- 2 893-386-B The next section of this manual shows an example of a file transfer using these steps with the Kermit file transfer program. Before you use the Kermit program or any other file transfer program, consult the documentation for that program.
