Troubleshooting Problems with Terminals

If your terminal seems to stop while processing (i.e., it "hangs") attempt the following measures to solve the issue:

Be sure the cable between the terminal and the system is secure.
Be sure the system is still on; check with other users.
Hold CTRL down and type Q or B. If output to the terminal has been suspended with CTRL+S, the CTRL+Q sequence will cause the output to resume. The CTRL+B sequence will unlock the keyboard if it was locked by the operator or the system. Note that the keyboard is locked by pressing CTRL+D.
Press CTRL+BREAK. If an ! or an * appears on the screen, type G or END and press ENTER. The G command will attempt to continue the hung process and the END command will return you to TCL.

NOTE	Certain processors, such as the CREATE-FILE processor, inhibit the CTRL+BREAK key sequence while they are running.

Turn the terminal off, wait a moment and then turn it on again. If an ! or an * appears on the screen, type G or END and press ENTER. The G command will attempt to continue the hung process and the END command will return you to TCL.
Call your system supplier for assistance.

NOTE	If you turn the terminal off and on again, the screen messages will be lost.
