DC Disable Connection
DC is entered at the basic level of CFS, and causes the specified connection to be terminated. If a BS2000 dialog task was still active under that connection, DCn will result in a console message "ABNORMAL TASK TERMINATION 22" (Line failure/ hardware error).
A subtask will also be terminated by the BS2000 /LOGOFF command.
Some connections, e.g. console-type connections, can only be terminated with a DC command.
