LOGGING INTO THE DECSERVER
==============================
To login to the DECserver you may be required by your server manager to enter a
login password. If you are not required to do so, go on to the next screen. If
you are, here are the steps to take to log in.
1 Press <RETURN> twice; a number sign (#) appears along with an audible "beep".
2 Enter the login password. (You get the password from your server manager.)
For example, to log in with the password A1B2C3...
<RETURN> <RETURN> enter <RETURN> twice
# A1B2C3 type the password (which is not echoed)
3 If you make a mistake, the prompt reappears (and the "beep") to let you try
again. You have several chances to enter the correct password.
4 If you use a dial-in modem, you have 60 seconds to respond to the # prompt
with the correct password. If you don't, the server disconnects your modem.
If you do not need to enter a login password, press <RETURN> twice to log into
your DECserver.
When you log in, an introductory line of text appears...
DECserver 200 Terminal Server V3.0 (BL20) - LAT V5.1
If your port does not have a permanent username defined, enter your name (1 to
16 keyboard characters) after the following text appears...
Please type HELP if you need assistance
Enter username>
The Local> prompt appears after you type your username.
If your port does have a permanent username, here's what you see...
Please type HELP if you need assistance
Local>
USING ONLINE HELP
===================
Online help is documentation about DECserver commands that is stored in server
memory. You can see this documentation interactively on your terminal while you
are using the DECserver. The HELP command gives you access to online help. You
can use it in two ways:
You can type HELP at the Local> prompt...
Local> HELP
This generates a succession of HELP "frames", "menus", and prompts. Frames are
made up of the information that can fit on one or more terminal screens. Menus
are lists of topics you can choose from.
Alternatively, you can specify topics and subtopics when you enter the HELP
command. For example...
Local> HELP SET PORT
This command produces online documentation that describes the SET PORT command.
SOME DEFINITIONS
==================
The primary function of the DECserver is to allow you to connect to "services"
offered on your network. A service can be a computer system that you can use
just as though your terminal were attached directly to the system, or it can be
a function offered by such a system. In addition, services can be set-up to
allow access to printers, dial-out modems, personal computers and terminal
switches. To connect to a service, you only need to know the service name.
A "service node" is a computer system or server that offers services.
A "session" is a connection to a service. You can have one or more simultaneous
sessions with one service, or more than one service. The connection you are
using at any one time is called your "current session". Your other sessions are
inactive, but can be resumed by using server commands or session switches.
"Service mode" is your environment when you interact with a service. For
example, if the service is a computer system, your environment is the same as a
terminal directly wired to the system. You can all use the system's commands
and resources.
"Local mode" is your environment when you interact with the DECserver using
commands entered at the Local> prompt.
CONNECTING TO A SERVICE
==========================
Use the local mode SHOW SERVICES command to display a list of services you can
use.
Local> SHOW SERVICES
To connect to a service (establish a session with the service) enter the
DECserver CONNECT command with the name of the service you want. For example,
for a service called SALES, enter the following command:
Local> CONNECT SALES
This command places you in service mode in an active session with the
service SALES.
RETURNING TO LOCAL MODE FROM A SERVICE SESSION
=====================================================
To return to local mode without ending your session, press <BREAK> or press your
local switch character. Both these characters are, in effect, DECserver
commands that instruct the server to go back to local mode.
The <BREAK> character must be set up to permit this (by default it is), and the
local switch character must be defined (by default it is not).
Use the HELP command for more details on setting up the <BREAK> character and
local switch character.
NOTE
Some modems interpret the BREAK character as a command to end
your dial-in connection. If you are using one of these modems,
do not use <BREAK> to return to local mode.
Your session, now inactive, is still your current session because it is the
session your were using most recently.
RESUMING YOUR SERVICE SESSION FROM LOCAL MODE
====================================================
To resume your current session (and service mode) while your are in local mode,
enter the DECserver RESUME command.
Local> RESUME
You go back to where you left off before returning to local mode.
DISCONNECTING FROM A SERVICE
=================================
To end your current session while in service mode, use the command that
terminates whatever process you are using. For example, you can terminate a
session on a VAX/VMS system by typing the VMS LOGOUT command. Refer to the
documentation for the service node that offers the service.
To end your current session while in local mode, enter the DECserver DISCONNECT
command.
Local> DISCONNECT
You cannot resume a service session after you end the connection with
DISCONNECT.
CONNECTING TO A SECOND SERVICE
==================================
The DECserver allows you to have several sessions at one time, to the same or to
different services. To connect to a second (or subsequent) service, simply enter
another CONNECT command from local mode, specifying the name of the service. For
example, to connect to the service PRODUCTION, enter the following command:
Local> CONNECT PRODUCTION
To resume one of your non-current sessions, use the FORWARDS command to switch
to your next session, or the BACKWARDS command to switch to your previous
session. Alternatively, you can use the RESUME command and specify the session
number. You can find this number from the SHOW SESSIONS display:
Local> RESUME SESSION 2
To disconnect a particular session, use the DISCONNECT command and specify the
session number. For example:
Local> DISCONNECT SESSION 1
LOGGING OUT OF THE DECSERVER
================================
To logout from the DECserver, enter the DECserver LOGOUT command (in local
mode).
Local> LOGOUT
LOGOUT disconnects all sessions. A DECserver message appears verifying the
logout.
Topic? help
HELP
HELP gives you on-line information about DECserver commands. HELP lets you
progress through a series of menus or enter specific HELP topics.
HELP [topic] [subtopic(s)]
Specify a topic or subtopic(s) when you need information about specific parts of
commands (e.g., HELP SHOW PORTS ACCESS).
The following conventions are used in the HELP descriptions:
o Slashes (/) in the title for a HELP topic mean that the text applies to more
than one command or optional keyword.
o Lowercase words in command syntax (for example, port-name) mean that you enter
a value from a list of possible values.
o Upper case keywords in command syntax (for example, SET PORT) mean that you
enter these keywords as shown.
o Brackets around a keyword or value, for example, [LOCAL], indicate options.
Choose one and only one option.
o Braces around keywords or values, for example, {DYNAMIC}, mean you must choose
one and only one of the included words.
You may perform any of the following actions while using online HELP:
o Type a question mark (?) to any help prompt to redisplay the HELP text
associated with that prompt.
o Press the RETURN key to return to the previous (sub)topic level. If you are
at the Topic? prompt level, you will return to the Local> prompt.
o Enter a (sub)topic keyword at the continuation prompt, resulting in the frame
associated with that keyword.
o Enter <CTRL/Z> to exit HELP from any prompt or level.
You may abbreviate any topic keyword following the same rules set forth for the
DECserver's local mode command language.
================
Topic? backwards
================
BACKWARDS
BACKWARDS lets you resume your 'previous' service session - the
session with the next lower session number than the current session. If
your current session is session one, the session with the highest
session number will be resumed.
BACKWARDS
If you have only one active session, that session resumes.
Topic? forwards
FORWARDS
Use this command to resume your 'next' service session - the session
with the next higher session number than the current session. If your
current session is already the highest session number, session one will
be resumed.
FORWARDS
If you have only one active session, that session resumes.
Topic? resume
RESUME
Use this command to resume a session when you are in local mode. If you do not
specify a session number, your current session resumes.
RESUME [SESSION number]
Additional help available for:
SESSION
RESUME Subtopic? session
RESUME SESSION
SESSION session-number lets you specify the session to resume
SHOW SESSIONS lists your sessions.

===============
Topic? broadcast
================
BROADCAST
Use BROADCAST to send a message to other DECserver ports. Your
message appears at the destination port device unless BROADCAST is
disabled for the port or the port device does not currently have local
access.
BROADCAST PORT port-number {"message-text"}
{ message-text }
The message-text may contain up to 115 keyboard characters. If you
enclose it in quotation marks ("), it is broadcast exactly as you type
it. If not, the server sends it in uppercase characters.
Additional help available for:
PORT
BROADCAST Subtopic? port
BROADCAST PORT
PORT port-number specifies which port receives the broadcast message
BROADCAST Subtopic?

SET
Use SET commands to change characteristics and options stored in the server's
operational database.
SET [PRIVILEGED]
[PORT ]
[SESSION ]
Additional help available for:
PORT PRIVILEGED SESSION
SET Subtopic? port
DEFINE/SET PORT
Use DEFINE PORT to change the port characteristics that take effect when the
port is next logged in. Use SET PORT to change the port characteristics that
you wish to take effect immediately, but only stay in effect until port logout.
{DEFINE} PORT port-characteristic(s)
{SET }
port-characteristic(s) are one or more port characteristics options
Additional HELP is available for the port-characteristics:

FLOW CONTROL
DEFINE/SET PORT Subtopic? autoconnect
DEFINE/SET PORT AUTOCONNECT
=================================
AUTOCONNECT allows the server to automatically connect the port to a service.
AUTOCONNECT operates upon abnormal termination of a connection or upon failure
to establish a requested connection. With a dedicated service or preferred
service, AUTOCONNECT automatically makes a connection to the service when the
port user logs in.
AUTOCONNECT {ENABLED }
{DISABLED} *
ENABLED allows the AUTOCONNECT function. DISABLED inhibits AUTOCONNECT.
DEFINE/SET PORT Subtopic? flow control
=======================================
DEFINE/SET PORT FLOW CONTROL
FLOW CONTROL specifies the characters or signals that control
data flow at your port.
FLOW [CONTROL] {CTS }
{DISABLED}
{DSR }
{XON } *
CTS means that CTS/RTS modem signals implement flow control.
DISABLED means that flow control is disabled.
DSR means that DSR/DTR modem signals implement flow control.
XON means that XON/XOFF characters implement flow control.
When using CTS or DSR flow control, MODEM CONTROL must be DISABLED.
You can specify a single direction for flow control. If you do not, control
applies to both ingoing and outgoing data.
{INPUT } FLOW [CONTROL] {ENABLED } *
{OUTPUT} {DISABLED}
INPUT controls data flow from your port device to the server port.
OUTPUT controls data flow from the server port to your port device.
DEFINE/SET PORT Subtopic? message codes
DEFINE/SET PORT MESSAGE CODES
MESSAGE CODES specifies whether message numbers appear with status and error
messages.
MESSAGE [CODES] {ENABLED } *
{DISABLED}
ENABLED permits the codes to appear. DISABLED inhibits message codes.
DEFINE/SET PORT Subtopic? remote modification
DEFINE/SET PORT REMOTE MODIFICATION
Use REMOTE MODIFICATION to control whether port characteristics can be modified
remotely by the service node side of a session.
REMOTE [MODIFICATION] {ENABLED }
{DISABLED} *
ENABLED specifies that port characteristics may be modified remotely.
DISABLED specifies that port characteristics can not be modified remotely.
DEFINE/SET PORT Subtopic? autoprompt
DEFINE/SET PORT AUTOPROMPT
AUTOPROMPT determines whether a service's login prompt is transmitted
automatically to the port when a session starts. Set AUTOPROMPT to DISABLED for
remote access ports or for port devices without keyboards.
AUTOPROMPT {ENABLED } *
{DISABLED}
ENABLED allows automatic appearance of a login message and prompt.
DISABLED inhibits a service's login message and prompt until the
user enters <RET>.
DEFINE/SET PORT Subtopic? speed
DEFINE/SET PORT SPEED
========================
SPEED specifies the port speed. It must match the speed parameter for the port
device. Use the INPUT and OUTPUT keywords for split speed operation.
[INPUT ] SPEED speed
[OUTPUT]
The speed value can be one of:
75, 110, 134, 150, 300, 600, 1200, 1800, 2000, 2400, 4800, 9600, 19200
The default is 9600.
INPUT is directed from the port device to the server.
OUTPUT is directed from the server to the port device.
DEFINE/SET PORT Subtopic? backward switch
DEFINE/SET BACKWARD SWITCH
Use BACKWARD SWITCH to set up a special character that allows you
to switch to the previous session for the port.
BACKWARD [SWITCH] {character}
{NONE } *
Control characters are recommended for switch characters.
NONE deletes a previous BACKWARD SWITCH character.
DEFINE/SET PORT Subtopic? forward switch
DEFINE/SET PORT FORWARD SWITCH
Use FORWARD SWITCH to set up a special character that allows you
to switch to the next session for the port.
FORWARD [SWITCH] {character}
{NONE } *
Control characters are recommended for switch characters.
NONE deletes a previous FORWARD SWITCH character.
