Disconnect a switched line (ISSUE DISCONNECT)

This command is used to break a line connection between a terminal and the processor, or to break a session between TCAM or VTAM® logical units, when the transaction is completed. If the terminal is a buffered device, the data in the buffers is lost.

When used with a VTAM terminal, ISSUE DISCONNECT, which does not become effective until the task completes, signs off the terminal, frees the COMMAREA, clears the next TRANID, stops any BMS paging, and, if autoinstall is in effect, deletes the terminal definition.
