DIS - logical or physical disconnect.

DIS [options]

-AB             -ALL            -HOLD
-NORM           -OFF            -SI id

-AB: requests an abnormal disconnect. All pending messages are destroyed. This is the default.
ALL: disconnects from all sessions, including suspended ones.
HOLD: does a logical disconnect but not a physical one. You remain connected to the terminal manager so that you can issue more DSA commands (e.g. a new connect).
NORM: requests a normal disconnect.
OFF: automatically logs off as well as disconnects.
-SI id: disconnects from a specified session (where "id" is the session ID of the session that you want to disconnect).

The DIS command can logically or physically disconnect your terminal from the terminal handler.
