1. If yours is the only terminal that is locked up, be sure to look at the port number that is locked.  This number is located at the top left corner of the screen.

2. Is the terminal is beeping.  If yes:

a. What are you doing (what program are you in)?

b. Beeping indicates an item lock with another terminal.  If you are trying to bill out a part number in Point of Sale, for instance, there might be another terminal with that part number on the screen in Inventory Entry.  Have the person in Inventory exit out, and the locked terminal should stop beeping.

c. If you have multiple stores, or cannot take the time to find out who has the item locked, you can find out by going to TCL from another terminal and typing LIST-LOCKS (IG.  This will show Group and Item locks.  The PIB# will give you the port that has the item locked.  You can also type LU to find out who is logged on that port number and get them out of the item they have locked.  Terminal should stop beeping.

3. Try typing Ctrl-Q at the locked terminal.

4. Turn terminal off and on.  After turning on, press enter several times to see if screen comes back.

5. Try typing Ctrl-Break at terminal.  If this works, the terminal probably is not locked, but there may be a software item lock as found in step 2, above.  Hit enter a couple of times, then check situation with steps found in #2.  If this still does not solve the problem, they may Ctrl-break again, and type END at the colons.

6. Try going to another terminal and at TCL, type RESET.DEV  #.  (# = locked port number)

7. At another terminal, at TCL, type RESET-USER #.

8. If none of these steps work, and this is the only locked terminal in their system, then:

a. Switch the terminal with a known working terminal.  If it does not work on a known working port and cable, be sure to validate that the baud rate is correct.  If baud is correct, the terminal has either lost it's settings or is blown.  Check terminal settings to make sure they have not been reset.  You can default the terminal to the original MFR settings, and set them back up.  To default the terminal:

1. Link MC2 terminals – Hold the 'G' key down while turning terminal on.  You can also reset settings by going into the setup (Shift-Select or Ctrl-Select), then pressing the Escape key to set back to defaults.  Set terminal back to normal setups.

2. ADDS terminals – Press Ctrl-Scroll Lock to get into setup.  Hit F13 to get to the reset menu.  Arrow to Reset Terminal and press the space bar.  F14 to exit.  If this doesn't work, then go back to setup, hit F13, then arrow to Default Terminal and press the space bar.  You can then set terminal back to our normal setups.

a. If the locked terminal works on another port, then there is probably a problem with the cable or port that the terminal was hooked to originally.  Check cable ends to make sure none of the pins have fallen out, or have been bent.

b. If the cable appears to be in good condition, switch the cable to a known working port, then try the terminal again on the same cable hooked to the new port.  Again, be sure baud rates are correct.  If it works on the new port, then there is a problem with the original port.  If it does not work on the new port, then there is a problem with the cable.  Switch the cable back to the original port one last time, sometimes simply removing and reseating the cable(s) is all it takes.

9. If all of the above fails, try going through a power-off procedure to reset all the ports, etc. 

Power Off procedure:

Everyone who can, log off.

At port 0 (preferably) type DM at Main Menu

Type POWER-OFF

You may need to hit enter a couple of times if the screen stops showing printer information.  This only happens with a larger customer with several printers.

When prompted, type Y to continue.

Wait for shutdown completed message, then wait 15 seconds, turn machine off, wait 15 seconds, turn machine on.  Machine will reboot on its own.
