DISCONN                                                CP Privilege Class:  Any

Use the DISCONN command to disconnect your terminal from the VM/370 system
while the virtual machine continues operation.  The format of the DISCONN
command is:
+----------+------------------------------------------------------------------+
| DISConn  | [HOld]                                                           |
+----------+------------------------------------------------------------------+
where:

HOld     specifies that the communication line is not to be disabled.  This
         option allows you to disconnect your terminal, and, at the same time,
         to avoid the process of telephone dialing into the system to access
         your virtual machine again. If specified, control returns to CP and
         the "VM/370 online" message is displayed.


Usage notes:

1.  The terminal remains disconnected until it is reconnected via a LOGON
    command.  The virtual machine is logged off 15 minutes after an attempt is
    made to read from the terminal or if the virtual machine goes into a
    disabled WAIT state.  The user should be aware that certain operating
    systems frequently issue "reads" to the console, which can cause the logoff
    time-out situation.

2.  If your terminal connection is broken because of terminal, line, or
    teleprocessing control unit errors, CP places the virtual machine in
    disconnect mode for up to 15 minutes and your virtual machine does not
    continue to run.  If you log on within 15 minutes, your virtual machine can
    continue operating.  Since many operands of the SET and TERMINAL commands
    default to OFF when you log on again, you have to reissue the SET and
    TERMINAL commands.  If you do not log on within the 15-minute interval, the
    virtual machine is logged off.

3.  Unless the CP command, SPOOL CONSOLE START, is issued to spool the virtual
    console output, all "writes" or output messages to the virtual console are
    ignored.  When the terminal is reconnected via the normal logon procedure,
    the terminal is placed in CP console function mode.  To resume execution of
    the virtual machine, enter the BEGIN command.

Response

When the DISCONN command is issued, the disconnect time message is issued.

DISCONNECT AT hh:mm:ss zone weekday mm/dd/yy
   is the response to the user who issued the command.

GRAF raddr ¦ LINE raddr ¦ DEV resid  DISCONNECT userid USERS = nnn
   is the response to the primary system operator informing him that the user
   represented by userid has been disconnected from the VM/370 system.  The
   response, nnn, is the total number of users remaining in the system.  DEV
   resid indicates the resource identification of a 3704/3705 line.
