Lesson 4 Any Problems?
Lesson 4 presents sources of information and some hints for solving
common terminal problems.
Sometimes things don't go as expected.
Sources of information
Two places provide detailed information about the way your terminal
works:
* The documentation or instructions that came with your particular
terminal.
* Other people. Often they are the fastest route to an answer.
When you need help with the computer, and you can't seem to find the
answer on your own, certain persons can help you:
Account Manager If it's a "how to" question, your account manager,
sometimes called the AM, probably has an answer.
Your AM creates groups in your account and gives
you your passwords. (The importance of accounts
and groups is presented in module 4.)
System Operator The system operator (or operator or manager of
operation) has charge of the console at any
particular time of the day. If your terminal locks
up on you and nothing that you do seems to help,
talk to your operator. If you can't log on, or if
your session or job is behaving oddly, the operator
can probably find the answer.
System Manager The system manager (or manager) is responsible for
ensuring that the computer is set up to meet the
needs of the users. Unless you have problems that
need some modification of the system itself, you
probably won't need the help of your system
manager.
Terminal not responding
Nothing appears on the screen.
* Some terminals take a moment or two to warm up and run through a
self-test.
* Press the Return key a couple of times.
If nothing appears on the screen after 15 or 20 seconds, do some
investigating:
* Is the terminal plugged in and turned on?
* Are all of the right cables attached?
* Is your connector line working?
If you are not sure how to turn on and connect your terminal, talk to the
operator, or consult the documentation that came with your terminal.
Terminal on but not responding
You can type on the keyboard. Letters and numbers appear on the screen,
but it looks as though the computer is not responding.
The terminal is probably in the wrong mode. The terminal has two working
modes:
Local In local mode, your terminal is completely on its
own. It does not interact with the computer. What
you type appears on the screen, but none of it goes
to the computer for processing. This is sometimes
called standalone mode. You do not want local mode
now.
Remote In remote mode, your terminal talks directly to the
computer and shows you the computer's responses.
You want remote mode.
Changing modeswith the softkeys
NOTE If you have an HP 150(TM), an HP Vectra(TM), or some other personal
computer connected to an HP 3000, your softkeys may behave
differently from the discussion that follows. If you are not using
an HP 2392 or an HP 700/92 Series terminal, consult the
documentation that came with your terminal.
Log on again. Enter:

Figure 2-3. Video Screen at Logon
Note that these boxes correspond to the f1 through f8 keys of your
keyboard in figure 2-3.
NOTE Some keyboards may have an additional set of function keys running
vertically on the left side; some have twelve function keys instead
of eight. For this exercise, focus on the function keys f1 through
f8 running horizontally across the top of your keyboard.
On the HP 2392 and the HP 700/92 Series terminals, two more keys sit
between f4 and f5:
Menu User System
Initial display
Compare the screen to the illustration in figure 2-3.
If the boxes along the bottom of the screen look different from those in
figure 2-3, press the key labeled like this:
User System
That should make the row of boxes on the screen look like the ones shown
in figure 2-3. (If you are having trouble, talk with your supervisor or
account manager.)
Right now, concentrate on the fourth box on the screen:
modes
It is controlled by the key labeled f4. Press the key labeled f4.
The eight boxes across the bottom of the screen should change to look
like those in figure 2-4.

Figure 2-4. Softkey Function Display
Notice that some keys change the label (and purpose) of other keys.
Once again look at the fourth
box:
REMOTE MODE
* Does an asterisk * appear inside the box, like this?
REMOTE MODE*
If it does, your terminal is already in remote mode and is ready
to communicate with the computer. Do not do anything more.
* Or is the asterisk missing?
REMOTE MODE
If the asterisk is missing, you are in local mode--the terminal is
cut off from the computer. You do not want that. Press the key
labeled f4.
That should change box 4 to this:
REMOTE MODE*
* An asterisk (*) appearing in a softkey box tells you that the
function displayed there is switched On.
* If no asterisk appears in a softkey box, you know that the
function displayed there is switched Off.
When you have set your terminal for remote mode, press the key labeled:
User System
You should see the original eight boxes that you first saw when you
logged on.
The other softkey keys
You may have guessed already that you can use the softkeys to make other
changes to other boxes.
These keys and the boxes they affect
allow you to change the configuration of your terminal. The
configuration settings tell your terminal how to behave:
* what to display
* how to display it
* whether to communicate with the computer
* how to communicate with the computer
* how to communicate with other devices
If you want to know more about configuring your terminal, or if you feel
you need to change the configuration, consult the documentation that came
with your terminal.
NOTE Unless there is very good reason for doing so, do not change the
configuration of your terminal without first getting advice from
your account manager or your supervisor.
Without knowing the effect of the changes you are making, you could
configure your terminal in a way that makes it completely
unworkable for you. You can recover from configuration mistakes,
but it's a nuisance.
Is the terminal locked up?
Sometimes the terminal screen seems to "freeze up."
* You type something and press Return, and nothing happens.
* You type and nothing at all happens.
You may have a hung terminal. There are remedies.
It is difficult to say exactly what happened. Most likely you
accidentally pressed CTRL at the wrong moment, or you pressed a
combination of keys that sent an unexpected signal to the computer.
Remedies
First, wait a few seconds. The computer may be busy executing a
high-priority program.
Next, ask others on your system whether they are having the same problem.
(There might be a power shutdown or a system shutdown.)
If you still have no solution to the problem, there are four remedies you
can try, in this order:
1. Soft reset.
2. Hard reset.
3. Turn the terminal off, then back on.
4. Talk to your account manager or supervisor.
NOTE If you have an HP 150(TM), an HP Vectra(TM), or some other personal
computer connected to an HP 3000, some of your keys may behave
differently from the discussion that follows. If you are not using
an HP 2392 or an HP 700/92 Series terminal, consult the
documentation that came with your terminal.
Soft reset.
Always try this first. It causes the least interruption to your work.
Hold down Shift. While holding it down, press Reset/Break.
This reset does not work if you press one key, let go, and then press the
other key.
Did anything change? Using a soft reset is the "gentle" way to regain
control of a hung terminal. You are still logged on, and all of your
work is intact.
Hard reset.
If a soft reset does not work, a hard reset may.
Press Shift and CTRL simultaneously. While you hold them down, press
Reset/Break.
Try that now.
Did the screen clear? Did you find the cursor in the upper left corner
of the screen?
Press Return to get the system prompt back.
Turn the terminal off.
If a soft reset and a hard reset have no effect, turn off the terminal
and turn it back on. If you have trouble finding the power switch,
consult the manual for your terminal or ask someone who uses the same
kind of terminal.
Talk to your account manager.
If your terminal is still hung, it is time to talk to your account
manager or your system operator.
Remedies - the pros and cons
Soft Reset This never disturbs any of the work that you are
doing, but it may not solve the problem.
Hard Reset This might erase your current work (what you have
been doing on the screen), but it usually frees a
hung terminal. It cannot be used to log off.
Turn Off/On This might erase some of your work. If your
terminal is not wired directly into your computer,
this method could log off your session. It usually
frees a hung terminal. Your operator knows whether
your terminal is wired directly.
Operator The operator may have to abort your session (force
a logoff). If your operator cannot remedy the
"hang," your terminal (or the line connecting it to
the computer) may need some kind of maintenance.
NOTE For the work that you will do in this tutorial, soft reset and hard
reset work equally well and cause you no serious interruptions,
although a hard reset does require you to press Return to get back
the system prompt.
