Disconnecting the Remote Line 

Entering the DI command initiates a clean disconnect from the telephone
line connected to the remote support modem port.  This command is valid
only from a remote console.  If a local operator attempts to use this
command, the system issues a message:

     Command may not be executed by a local user. (APERR 15)

The system displays the message, Remote line is disconnected, when the
line is disconnected.
