Freezing and Thawing a Terminal
The display shows:
Freezing and Thawing a Terminal
When you freeze a Safeguard terminal, all logon attempts at that terminal are
disallowed. For example, this command freezes the terminal $TFOX.#T014:
FREEZE TERM $tfox.#t014
To reenable users to log on at the terminal:
THAW TERM $tfox.t014
The FREEZE and THAW commands are valid only for a Safeguard terminal. If no
terminal definition exists for a terminal, FREEZE and THAW have no effect on that
terminal.
Deleting a Terminal Definition
You can delete a terminal definition so that the terminal is no longer controlled by the
Safeguard software. After you delete the definition, you must start another command
interpreter, such as TACL, to control the logon dialog at that terminal.
For example, this command deletes the definition for the terminal $TFOX.#T015:
=DELETE TERMINAL $tfox.#t015
This terminal is not usable until you start another command interpreter to handle its
logon dialog.
