Lesson 4 presents sources of information and some hints for solving common terminal problems. Sometimes things don't go as expected. Two places provide detailed information about the way your terminal works:
When you need help with the computer, and you can't seem to find the answer on your own, certain persons can help you:
Nothing appears on the screen.
If nothing appears on the screen after 15 or 20 seconds, do some investigating:
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. 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:
Log on again. Enter:
Note that these boxes correspond to the f1 through f8 keys of your keyboard in figure 2-3.
On the HP 2392 and the HP 700/92 Series terminals, two more keys sit between f4 and f5:
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:
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:
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. Notice that some keys change the label (and purpose) of other keys. Once again look at the fourth box:
When you have set your terminal for remote mode, press the key labeled:
You should see the original eight boxes that you first saw when you logged on. 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:
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.
Sometimes the terminal screen seems to "freeze up."
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. 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:
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. 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. 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.
