HP OpenVMS Systems Documentation

Breaks the connection between a physical terminal and a virtual terminal. After the physical terminal is disconnected, both the virtual terminal and the process using it remain on the system.

Requires that your physical terminal is connected to a virtual terminal.

Format

DISCONNECT

Parameters

None.

Description

Use the DISCONNECT command to disconnect a physical terminal from a virtual terminal and its associated process. The virtual terminal and the process remain on the system, so you can use the CONNECT command to reconnect to the process later. (For more information about virtual terminals and how to connect to them, see the description of the CONNECT command.) To terminate a process connected to a virtual terminal, use the LOGOUT command.

After you are disconnected from a virtual terminal, you can use the physical terminal to log in again.

You can use the DISCONNECT command only if your physical terminal is connected to a virtual terminal.

Qualifier

/CONTINUE

/NOCONTINUE (default)

Controls whether the CONTINUE command is executed in the current process just before connecting to another process. This procedure permits an interrupted image to continue processing after the disconnection until the process needs terminal input or attempts to write to the terminal. At that point, the process waits until the physical terminal is reconnected to the virtual terminal.

Examples

$ DISCONNECT
      

This command disconnects a physical terminal from a virtual terminal, but does not log the process out. Now you can use the physical terminal to log in again.

$ RUN PAYROLL
[Ctrl/Y]
$ DISCONNECT/CONTINUE
 

 
 
      

In this example, the RUN command is entered from a physical terminal that is connected to a virtual terminal. After the image PAYROLL.EXE is interrupted, the DISCONNECT command disconnects the physical and the virtual terminals without logging out the process. The /CONTINUE qualifier allows the image PAYROLL.EXE to continue to execute until the process needs terminal input or attempts to write to the terminal. At that point, the process waits until the physical terminal is reconnected to the virtual terminal; however, you can use the physical terminal to log in again and perform other work.
