This manual describes how to use the Model 3395 Terminal Server on an local area network (LAN). It explains how to use terminal server commands, and how to tailor some terminal server characteristics to suit your needs. This manual is for people who want to use the terminal server to gain access to resources on the network, rather than the individual who installs and manages the terminal server hardware and software.

Page 11: Chapter 1 - Getting Started
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). These resources include a variety of hosts, workstations, and printers, as well as other SynOptics terminal servers.
Page 12: Expanding The Network With The Terminal Server
These devices allow terminal server users to access LAN resources in many different ways, and provide additional resources to LAN users. Figure 1-2 shows an example of a Model 3395/3395A Terminal Server on the LAN, with several different devices connected to it.
Page 13: Using The Terminal Server
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 the terminal server • Logging on to a terminal server port •...
Page 14: Logging On To A Terminal Server Port
Kerberos is an Internet network authentication service that may exist on your terminal server. It requires that you enter a Kerberos password to gain access to the terminal server. The Kerberos password prompt appears after the Username> prompt in the Model 3395 Terminal Server login sequence, and looks like this: Enter user password>...
Page 15: Managing Sessions
LAT service, a Telnet host, an IBM host, or another terminal server after you log in to the terminal server port. The Model 3395/3395A Terminal Server allows you to open several sessions simultaneously, and move among them while you work. The next sections explain how to establish and manage sessions.
Page 16: Suspending A Session
Getting Started 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. To suspend a session, press the Break key or the local switch character during the session. (A local switch character is a control character sequence that you or the network manager can define.
Page 17: Disconnecting From A Session
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.
Page 18: 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. If you work in a UNIX environment, you may want to use these aliases because they will be more familiar to you than the Model 3395/3395A commands. Instead of the terminal server HELP command, for example, you can enter the MAN command.
Page 19: Summary
Getting Started 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. You can suspend sessions and establish new sessions, so that you have several simultaneous connections.
Page 20: Chapter 2 - The User Interface
This chapter describes how to use the terminal server command interface and the terminal server menu interface. It includes these topics: • Entering commands • Editing the command line • Assigning session management functions to keyboard characters • Session switching characters •...
Page 21: Table 2-1 Editing Characters
The User Interface 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. At most terminals, you can use the SHOW|LIST PORTS ALTERNATE CHARACTERISTICS command to check the control character sequences for the editing functions at your port.
Page 22: Assigning Session Management Functions To Keyboard Characters
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. Instead of retyping the whole command line, however, you could use the up-arrow key or <CTRL><B>...
Page 23: Assigning A Local Switch Character
The User Interface 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. Assigning a Local Switch Character If your terminal or workstation does not have a Break key, you must define a local switch character to suspend a session.
Page 24: Telnet Session Management Characters
Returns the session to the local operating system command prompt. If you press the Telnet Attention key during a Telnet session at a Model 3395/3395A Terminal Server, the remote terminal server port passes the break request to the host or device where it is connected.
Page 25: Using The Terminal Server Menu
The User Interface 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>...
Page 26 Some commands have options that are available only at Nonprivileged or Privileged ports, and the command descriptions indicate this. For more information about commands available at Nonprivileged and Privileged ports, see Commands Reference for the Model 3395/3395A Terminal Server.
Page 27: Viewing And Changing Information In The Terminal Server Databases
UNIX equivalents of frequently used Model 3395/3395A commands. You can enter these equivalents, or aliases, at the TS3395> prompt just as you would enter the Model 3395/3395A commands to produce the same results. Table 3-1 shows the UNIX aliases for Model 3395/3395A commands.
Page 28: Backwards
BACKWARDS Reopen the next available lower-numbered session The BACKWARDS command reopens the next available, lower-numbered session already established at your port. Use the SHOW SESSIONS command to display information about active sessions, including their session numbers. N o t e s The terminal server assigns a number to each session you establish.
Page 29 BACKWARDS TS3395> backwards TS3395 -012- FINANCE.SUN.COM session 1 resumed The user's current session is now session 1. If this user suspended session 1 and entered the BACKWARDS command again, the terminal server would reopen session 3 at UNIX.HOST.COM, because session 3 is next on the rotating list. Related Commands These commands provide functions that are useful with or similar to the BACKWARDS command:...

TS3395> lat connect lasernode vax1 destination port_2 TS3395 You have reached LASER Username: 4 . This command does not use a service name. In the absence of this information, the command interface searches for a predefined LAT preferred service.
Page 44: Lock
L O C K Temporarily disable access to a terminal server port The LOCK command disables access to a terminal server port without terminating active sessions or logging out the port. The interface prompts you for a password before it locks the port. You use this password to “unlock” the port when you want to regain access to it.
Page 45: Logout Port
LOGOUT PORT Log out of the terminal server port The LOGOUT PORT command logs you out of the terminal server port, and terminates any active sessions. N o t e s Users at Secure ports can only log out of their own port. UNIX alias: Syntax LOGOUT [PORT]...
Page 46: Resume
R E S U M E Reopen an active session The RESUME command reopens a session that you specify in the command line, or the current session. Use the SHOW SESSIONS command to obtain a list of active sessions and their session numbers. N o t e s If you enter the RESUME command without specifying a session, the terminal server reopens the current session.
Page 47 RESUME Examples This command reopens a session using a session number. TS3395> resume session 3 This command reopens a session using a LAT service name. TS3395> resume financevax This command reopens a session using an Internet address. TS3395> resume 140.178.65.119 Related Commands These commands provide functions that are useful with or similar to the RESUME command:...
Page 48: Rlogin
RLOGIN Log on to a host through the terminal server command interface The RLOGIN command allows you to log on to a host through the terminal server. To do this, the terminal server passes a username for the remote host or a username for a remote terminal server port from the RLOGIN command line.
Page 49 RLOGIN Examples 1 . This command has no host username for the host UNIXSUN. The terminal server uses the port username to log on to the host. TS3395> TS3395 The shell prompt on UNIXSUN indicates that the RLOGIN request was successful. The response you see may be different.
Page 50: Script
N o t e s Script files reside on a host system and contain a collection of Model 3395/3395A Terminal Server commands. You or the network manager can create these scripts with the host's text editor if you have the appropriate privileges on the host. You can execute a script file with the SCRIPT command, or the network manager can specify that the terminal server execute a script automatically when you log on to a port.
Page 51 SCRIPT The terminal server's response to this command depends on the contents of the script file. At some ports, the commands in the script appear on the screen as the terminal server executes them. If the file contains a command such as CONNECT or RLOGIN, the user might see the logon banner of a remote host.
Page 52: Set Port
Users at Privileged ports can define and set these and other characteristics, as well as the characteristics of other ports. See Commands Reference for the Model 3395/3395A Terminal Server for information about the characteristics of the DEFINE|SET PORT commands that are accessible at Privileged and Nonprivileged ports.
Page 53 Reopen the next lower-numbered session during the [NONE]* current session, without returning to the Model 3395/3395A command interface when you enter this character or control character sequence. If NONE, do not enable a backward switch character at this port. Use this keyword to disable a previously defined backward switch character.
Page 54 Telnet session, when you use this character or control character sequence. If you have established the Telnet session through another Model 3395/3395A Terminal Server port, the remote terminal server port passes a break sequence to the Telnet host when you use this character.

XCONNECT XCONNECT Establish a session with an XDM host The XCONNECT command attempts to establish a session with an XDM host for terminal servers with the Xremote protocol enabled. N o t e s Not all terminal servers have the Xremote protocol enabled. If it is enabled, you can either provide the domain name or Internet address of an XDM host in the command line, or simply enter the XCONNECT command.

Page 103: Zero Counters
ZERO COUNTERS Reset port counters to zero The ZERO COUNTERS command resets the port counters to zero. Use the SHOW PORT COUNTERS command to display the counters at your port. N o t e s Users at Secure and Nonprivileged ports can only reset the counters of their own ports. These ports require that you use the PORT keyword and the port-list variable to specify your port number.
Page 104: Chapter 4 - Tn3270 Sessions
You can establish sessions over the LAN with an IBM host through the terminal server if the host has a Telnet server that supports the TN3270 protocol. When you log on to the IBM host, the terminal server software redefines the functions of the keys on your terminal's keyboard to emulate those of an IBM 3270 Model 5 or Model 2 display station.
Page 105: Using The Show Port Keymap Command
TN3270 Sessions port could be VT100, VT220-8, ANSI, or a another type defined by the network manager. The list of Enabled Characteristics includes TN3270 EOR, TN3270 ErrorLock, and TN3270 XtdAttrs. Note: If the TN3270 characteristic is not enabled, you can still establish a session with an IBM host, but your keyboard will not function properly and the screen will be incorrectly formatted.
Page 106: Using Hot Keys
Once the terminal server establishes a session with the IBM host, the terminal server software begin IBM 3270 terminal emulation. To check the functions of keys during a session, use the <CTRL><X> key sequence. This key sequence displays a table similar to the SHOW PORT KEYMAP display. Tables 4-1, 4-2, and 4-3 at the end of this chapter show 3270 keyboard functions and the corresponding keys on terminal types that are included in the software.

Page 113: Chapter 5 - Using The Multisessions Feature
MULTISESSIONS is the DEC server characteristic that controls the port where the terminals are connected. This characteristic does not affect the multiple session support feature of the Model 3395/3395A Terminal Server, which is available to all terminal server users. Managing Sessions Within Windows When you log in to a multisessions port, the terminal creates two windows where you can establish and manage sessions.
Page 114: Establishing The First Session
The multisessions terminal tracks the current session according to the window where it appears. If the session appears in window 2, the terminal considers the session number 2, even if the Model 3395/3395A Terminal Server session number is 1 or 3. The multisessions software always opens the first session in window 1.

Page 116: Establishing The Second Session
Multisessions You can override the multisessions interface and bring up the Model 3395/3395A command interface in two ways. You can enter the name LOCAL at the multisessions prompt, and this calls up the TS3395> prompt. Or, if no preferred service exists, you can press the <Return> key several times at the multisessions prompt, which calls up the TS3395>...
Page 117: Establishing Three Or More Sessions
Remember that the session number in the lower-left corner of the screen is the multisessions window number, not the Model 3395/3395A Terminal Server session number. You could have four active sessions, and reopen session 3 in window 1 and session 4 in window 2. If the cursor appears in window 1, the session number on the screen will be 1 to reflect the multisessions window number, not the terminal server session number.
Page 118: Backwards
Multisessions BACKWARDS The BACKWARDS command reopens the next lower-numbered session that does not already appear in a window. The session you reopen with the BACKWARDS command appears in the window where you entered the command. For example, a port could have four active sessions, numbered 1, 2, 3, and 4. Session 2 appears in the top window, and session 3 appears in the bottom window.

MULTISESSIONS characteristic. The local switch character calls up the Model 3395/3395A command processor at the window where you hit the character. The forward switch and backward switch characters behave somewhat differently from within windows, and these differences are described below.
Page 120: Backward Switch
Multisessions Backward Switch The backward switch character reopens the next lower-numbered session that does not already appear in a window. The session you reopen with the backward switch character appears in the window where you entered it. For example, a port could have four active sessions, numbered 1, 2, 3, and 4. Session 2 appears in the top window, and session 3 appears in the bottom window.

3. Set the data transparency of the session to PASSALL if the file transfer program requires it. To do this, suspend the session and return to Model 3395/3395A local command mode and use the SET SESSION command.
Page 122: Transferring A File With The Kermit File Transfer Program
Transferring Files 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. Transferring a File With the Kermit File Transfer Program This section describes a file transfer from a PC to a host with the Kermit file transfer program.

Chris starts up Kermit on FinanceVAX: applications:KERMIT VMS KERMIT - 32 version 3.2.076-a Default terminal for transfers is: _VTA463: (In this example, a directory called "applications" contains the Kermit program. The organization of directories and files varies on different hosts.
Page 125 7. Exit from the file transfer program on the host and terminate the session with the host. To end the file transfer session, Chris first enters the Kermit FINISH command at the PC to notify the host that he has no more files to transfer. Then he connects to the Kermit program on FinanceVAX , and shuts it down.
